VisualAge C++, Version 5.5 for AIX 5L for IA-64, Beta 3 Release
Usage:
xlC [ option | inputfile ]...
xlc [ option | inputfile ]...
cc [ option | inputfile ]...
c89 [ option | inputfile ]...
xlC_r [ option | inputfile ]...
xlc_r [ option | inputfile ]...
cc_r [ option | inputfile ]...
xlC_r4 [ option | inputfile ]...
xlc_r4 [ option | inputfile ]...
cc_r4 [ option | inputfile ]...
Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,
where <key> selects the file lib<key>.a.
-L<dir> Search in directory <dir> for files specified by -l<key>.
-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p <Currently not supported>
Generate profiling support code. Same as -qprofile=p.
-pg <Currently not supported>
Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.
-Q (C++) Turns on inlining.
-Q! (C++) Turns off inlining.
-Q<x>, -qinline<x>
(C) Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.
-S Produce a .s file for any source file processed by the
compiler.
-t<x> Apply prefix from the -B option to the specified program <x>,
where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor
m = 'munch' utility (C++)
f = C++ name demangler utility (C++)
<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.
-w Suppress informational, language-level, and
warning messages.
-W<x,y> Give the options <y> to the compiler program <x>
where x can be one or more of the following:
<p,c,b,i,a,l,I,m,f>
-y<x> <Currently not supported>
Specify compile-time rounding of constant floating-point
expressions, where <x> can be one of the following:
n = round to nearest
m = round toward minus infinity
p = round toward positive infinity
z = round toward zero.
2. Keyword options:
Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand
code inline.
cpluscmt (C) Permit "//" to introduce a comment that lasts
until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).
dbxextra Generate symbol table information for unreferenced
variables. By default such information is not generated
thus reducing the size of the executable compiled with
the "-g" option. Same as -qsymtab=unref.
digraph Allow special digraph
dollar Allow '$' as an identifier character
flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.
fold Specifies that constant floating-point expressions
are to be evaluated at compile time.

you use "-g" and the symbolic debugger.
heapdebug <Currently not supported>
Enables debug versions of memory management functions.
idirfirst Specify the search order for files included with
the #include "file_name" directive. Use -qidirfirst
with the -Idirectory option. If -qidirfirst option
is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.
list Produce an object listing; output goes to .lst file.
listopt Display the settings of all options; output goes
to .lst file.

which will be replaced by the length in bytes.
makedep Creates an output file that contains targets suitable for
inclusion in a description file for the AIX make command.
mbcs String literals and comments can contain DBCS
characters (same as dbcs option).
noprint Direct listing to /dev/null.
nostdinc Specify which files are included with the #include
"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the
source listing, if the SOURCE option is in effect.
source Produce a source listing; output goes to .lst file.
srcmsg Reconstruct source lines in error along with the
diagnostic messages in the stderr file.
statsym Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the
virtual function table for a class where the first
non-inline virtual member function is declared. If
-qnovftable is specified, then no virtual function tables
are produced.
warn64 Enables checking for possible pointer-to-integer truncation.
xcall Generate code to static routines within a compilation
unit as if they were external routines.

constants.
int is the default, and causes enum variables to be
treated as though they were of type signed int
depending on the range of the enum constants.

Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,
where <key> selects the file lib<key>.a.
-L<dir> Search in directory <dir> for files specified by -l<key>.
-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p <Currently not supported>
Generate profiling support code. Same as -qprofile=p.
-pg <Currently not supported>
Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.
-Q (C++) Turns on inlining.
-Q! (C++) Turns off inlining.
-Q<x>, -qinline<x>
(C) Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.
-S Produce a .s file for any source file processed by the
compiler.
-t<x> Apply prefix from the -B option to the specified program <x>,
where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor
m = 'munch' utility (C++)
f = C++ name demangler utility (C++)
<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.
-w Suppress informational, language-level, and
warning messages.
-W<x,y> Give the options <y> to the compiler program <x>
where x can be one or more of the following:
<p,c,b,i,a,l,I,m,f>
-y<x> <Currently not supported>
Specify compile-time rounding of constant floating-point
expressions, where <x> can be one of the following:
n = round to nearest
m = round toward minus infinity
p = round toward positive infinity
z = round toward zero.
2. Keyword options:
Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand
code inline.
cpluscmt (C) Permit "//" to introduce a comment that lasts
until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).
dbxextra Generate symbol table information for unreferenced
variables. By default such information is not generated
thus reducing the size of the executable compiled with
the "-g" option. Same as -qsymtab=unref.
digraph Allow special digraph
dollar Allow '$' as an identifier character
flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.
fold Specifies that constant floating-point expressions
are to be evaluated at compile time.
fullpath Specifies the path information stored for files when
you use "-g" and the symbolic debugger.
heapdebug <Currently not supported>
Enables debug versions of memory management functions.
idirfirst Specify the search order for files included with
the #include "file_name" directive. Use -qidirfirst
with the -Idirectory option. If -qidirfirst option
is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.
list Produce an object listing; output goes to .lst file.
listopt Display the settings of all options; output goes
to .lst file.
nolongdouble
Decrease long double size from 80 to 64 bits.

64-bit mode.
longlong Allow long long integers.
macpstr Allow '\p' as the first character of a string constant
which will be replaced by the length in bytes.
makedep Creates an output file that contains targets suitable for
inclusion in a description file for the AIX make command.
mbcs String literals and comments can contain DBCS
characters (same as dbcs option).
noprint Direct listing to /dev/null.
nostdinc Specify which files are included with the #include
"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the
source listing, if the SOURCE option is in effect.
source Produce a source listing; output goes to .lst file.
srcmsg Reconstruct source lines in error along with the
diagnostic messages in the stderr file.
statsym Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the
virtual function table for a class where the first
non-inline virtual member function is declared. If
-qnovftable is specified, then no virtual function tables
are produced.
warn64 Enables checking for possible pointer-to-integer truncation.
xcall Generate code to static routines within a compilation
unit as if they were external routines.

for enum variables based on the range of the enum
constants.
int is the default, and causes enum variables to be
treated as though they were of type signed int
depending on the range of the enum constants.

Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,

-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.

-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.

-Q! (C++) Turns off inlining.
-Q<x>, -qinline<x>
(C) Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.
-S Produce a .s file for any source file processed by the
compiler.
-t<x> Apply prefix from the -B option to the specified program <x>,
where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor
m = 'munch' utility (C++)
f = C++ name demangler utility (C++)
<Currently not supported>

<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.

where x can be one or more of the following:
<p,c,b,i,a,l,I,m,f>
-y<x> <Currently not supported>

expressions, where <x> can be one of the following:
n = round to nearest

2. Keyword options:
Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.

until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).

flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.

is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.

"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.

roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the

persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.

that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at

not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated

xlC_r: 1501-212 command option -version is incorrect for this Operating System platform - ignored
VisualAge C++, Version 5.5 for AIX 5L for IA-64, Beta 3 Release
Usage:
xlC [ option | inputfile ]...
xlc [ option | inputfile ]...
cc [ option | inputfile ]...
c89 [ option | inputfile ]...
xlC_r [ option | inputfile ]...
xlc_r [ option | inputfile ]...
cc_r [ option | inputfile ]...
xlC_r4 [ option | inputfile ]...
xlc_r4 [ option | inputfile ]...
cc_r4 [ option | inputfile ]...
Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,
where <key> selects the file lib<key>.a.
-L<dir> Search in directory <dir> for files specified by -l<key>.
-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p <Currently not supported>
Generate profiling support code. Same as -qprofile=p.
-pg <Currently not supported>
Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.
-Q (C++) Turns on inlining.
-Q! (C++) Turns off inlining.
-Q<x>, -qinline<x>
(C) Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.
-S Produce a .s file for any source file processed by the
compiler.
-t<x> Apply prefix from the -B option to the specified program <x>,
where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor
m = 'munch' utility (C++)
f = C++ name demangler utility (C++)
<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.
-w Suppress informational, language-level, and
warning messages.
-W<x,y> Give the options <y> to the compiler program <x>
where x can be one or more of the following:
<p,c,b,i,a,l,I,m,f>
-y<x> <Currently not supported>
Specify compile-time rounding of constant floating-point
expressions, where <x> can be one of the following:
n = round to nearest
m = round toward minus infinity
p = round toward positive infinity
z = round toward zero.
2. Keyword options:
Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand
code inline.
cpluscmt (C) Permit "//" to introduce a comment that lasts
until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).
dbxextra Generate symbol table information for unreferenced
variables. By default such information is not generated
thus reducing the size of the executable compiled with
the "-g" option. Same as -qsymtab=unref.
digraph Allow special digraph
dollar Allow '$' as an identifier character
flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.
fold Specifies that constant floating-point expressions
are to be evaluated at compile time.
fullpath Specifies the path information stored for files when
you use "-g" and the symbolic debugger.
heapdebug <Currently not supported>
Enables debug versions of memory management functions.
idirfirst Specify the search order for files included with
the #include "file_name" directive. Use -qidirfirst
with the -Idirectory option. If -qidirfirst option
is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.
list Produce an object listing; output goes to .lst file.
listopt Display the settings of all options; output goes
to .lst file.

64-bit mode.
longlong Allow long long integers.
macpstr Allow '\p' as the first character of a string constant
which will be replaced by the length in bytes.
makedep Creates an output file that contains targets suitable for
inclusion in a description file for the AIX make command.
mbcs String literals and comments can contain DBCS
characters (same as dbcs option).
noprint Direct listing to /dev/null.
nostdinc Specify which files are included with the #include
"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the
source listing, if the SOURCE option is in effect.
source Produce a source listing; output goes to .lst file.
srcmsg Reconstruct source lines in error along with the
diagnostic messages in the stderr file.
statsym Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the
virtual function table for a class where the first
non-inline virtual member function is declared. If
-qnovftable is specified, then no virtual function tables
are produced.
warn64 Enables checking for possible pointer-to-integer truncation.
xcall Generate code to static routines within a compilation
unit as if they were external routines.
xref Produce a cross-reference listing containing
only referenced names.

exec: /usr/bin/pg(/usr/bin/pg,/usr/vac/exe/default_msg/vac.help,NULL)
VisualAge C++, Version 5.5 for AIX 5L for IA-64, Beta 3 Release
Usage:
xlC [ option | inputfile ]...
xlc [ option | inputfile ]...
cc [ option | inputfile ]...

cc_r [ option | inputfile ]...
xlC_r4 [ option | inputfile ]...
xlc_r4 [ option | inputfile ]...
cc_r4 [ option | inputfile ]...
Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:

not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.

-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza

description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.

<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.

Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.

until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).

flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.

is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.

"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the

persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the

VisualAge C++, Version 5.5 for AIX 5L for IA-64, Beta 3 Release
Usage:
xlC [ option | inputfile ]...
xlc [ option | inputfile ]...
cc [ option | inputfile ]...
c89 [ option | inputfile ]...
xlC_r [ option | inputfile ]...
xlc_r [ option | inputfile ]...

Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,
where <key> selects the file lib<key>.a.
-L<dir> Search in directory <dir> for files specified by -l<key>.
-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p <Currently not supported>
Generate profiling support code. Same as -qprofile=p.
-pg <Currently not supported>
Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.
-Q (C++) Turns on inlining.
-Q! (C++) Turns off inlining.
-Q<x>, -qinline<x>
(C) Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.
-S Produce a .s file for any source file processed by the
compiler.
-t<x> Apply prefix from the -B option to the specified program <x>,
where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor
m = 'munch' utility (C++)
f = C++ name demangler utility (C++)
<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.
-w Suppress informational, language-level, and
warning messages.
-W<x,y> Give the options <y> to the compiler program <x>
where x can be one or more of the following:
<p,c,b,i,a,l,I,m,f>
-y<x> <Currently not supported>
Specify compile-time rounding of constant floating-point
expressions, where <x> can be one of the following:
n = round to nearest
m = round toward minus infinity
p = round toward positive infinity
z = round toward zero.
2. Keyword options:
Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand
code inline.
cpluscmt (C) Permit "//" to introduce a comment that lasts
until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).
dbxextra Generate symbol table information for unreferenced
variables. By default such information is not generated
thus reducing the size of the executable compiled with
the "-g" option. Same as -qsymtab=unref.
digraph Allow special digraph
dollar Allow '$' as an identifier character
flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.
fold Specifies that constant floating-point expressions
are to be evaluated at compile time.

you use "-g" and the symbolic debugger.
heapdebug <Currently not supported>
Enables debug versions of memory management functions.
idirfirst Specify the search order for files included with
the #include "file_name" directive. Use -qidirfirst
with the -Idirectory option. If -qidirfirst option
is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.
list Produce an object listing; output goes to .lst file.

inclusion in a description file for the AIX make command.
mbcs String literals and comments can contain DBCS
characters (same as dbcs option).
noprint Direct listing to /dev/null.
nostdinc Specify which files are included with the #include
"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the
source listing, if the SOURCE option is in effect.
source Produce a source listing; output goes to .lst file.
srcmsg Reconstruct source lines in error along with the
diagnostic messages in the stderr file.
statsym Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the
virtual function table for a class where the first
non-inline virtual member function is declared. If
-qnovftable is specified, then no virtual function tables
are produced.

VisualAge C++, Version 5.5 for AIX 5L for IA-64, Beta 3 Release
Usage:
xlC [ option | inputfile ]...
xlc [ option | inputfile ]...
cc [ option | inputfile ]...
c89 [ option | inputfile ]...
xlC_r [ option | inputfile ]...
xlc_r [ option | inputfile ]...
cc_r [ option | inputfile ]...
xlC_r4 [ option | inputfile ]...
xlc_r4 [ option | inputfile ]...
cc_r4 [ option | inputfile ]...
Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,
where <key> selects the file lib<key>.a.
-L<dir> Search in directory <dir> for files specified by -l<key>.
-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p <Currently not supported>
Generate profiling support code. Same as -qprofile=p.
-pg <Currently not supported>
Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.
-Q (C++) Turns on inlining.
-Q! (C++) Turns off inlining.
-Q<x>, -qinline<x>
(C) Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.
-S Produce a .s file for any source file processed by the
compiler.
-t<x> Apply prefix from the -B option to the specified program <x>,
where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor
m = 'munch' utility (C++)
f = C++ name demangler utility (C++)
<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.
-w Suppress informational, language-level, and
warning messages.
-W<x,y> Give the options <y> to the compiler program <x>
where x can be one or more of the following:
<p,c,b,i,a,l,I,m,f>
-y<x> <Currently not supported>
Specify compile-time rounding of constant floating-point
expressions, where <x> can be one of the following:
n = round to nearest
m = round toward minus infinity
p = round toward positive infinity
z = round toward zero.
2. Keyword options:
Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand
code inline.
cpluscmt (C) Permit "//" to introduce a comment that lasts
until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).
dbxextra Generate symbol table information for unreferenced
variables. By default such information is not generated
thus reducing the size of the executable compiled with
the "-g" option. Same as -qsymtab=unref.
digraph Allow special digraph
dollar Allow '$' as an identifier character
flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.
fold Specifies that constant floating-point expressions
are to be evaluated at compile time.
fullpath Specifies the path information stored for files when
you use "-g" and the symbolic debugger.
heapdebug <Currently not supported>
Enables debug versions of memory management functions.
idirfirst Specify the search order for files included with
the #include "file_name" directive. Use -qidirfirst
with the -Idirectory option. If -qidirfirst option
is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.
list Produce an object listing; output goes to .lst file.
listopt Display the settings of all options; output goes
to .lst file.
nolongdouble
Decrease long double size from 80 to 64 bits.
longlit Changes implicit type selection for integer constants in
64-bit mode.
longlong Allow long long integers.
macpstr Allow '\p' as the first character of a string constant
which will be replaced by the length in bytes.
makedep Creates an output file that contains targets suitable for
inclusion in a description file for the AIX make command.
mbcs String literals and comments can contain DBCS
characters (same as dbcs option).
noprint Direct listing to /dev/null.
nostdinc Specify which files are included with the #include
"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the
source listing, if the SOURCE option is in effect.
source Produce a source listing; output goes to .lst file.
srcmsg Reconstruct source lines in error along with the
diagnostic messages in the stderr file.
statsym Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the
virtual function table for a class where the first
non-inline virtual member function is declared. If
-qnovftable is specified, then no virtual function tables
are produced.
warn64 Enables checking for possible pointer-to-integer truncation.
xcall Generate code to static routines within a compilation
unit as if they were external routines.
xref Produce a cross-reference listing containing
only referenced names.

itanium Produce an object that contains instructions
that will run on Itanium hardware platform
The default is -qarch=ia64. If the -qarch option is
specified without the -qtune=<option>, the compiler
uses the default -qtune value for the specified
Architecture, which is currently -qtune=itanium.
assert=<option>
Specifies the aliasing assertion to be applied to
your compilation unit.
The available options are:
typ Pointers to different types are never aliased.

Specify which data items are imported. If no names are
specified, all data items are assumed to be imported.
This is the default.
datalocal=<name1>:<name2>: ...
Specify which data items are local. If no names are
specified, all data items are assumed to be local.
enum=<enumopt>
Specify whether minimum-sized enumerated types will be
produced or not. <enumopt> can be either small, int,
(C++)intlong, 1, 2, 4 or 8.
small denotes that either one, two, four or eight (valid
in 64-bit mode only) bytes of storage will be allocated
for enum variables based on the range of the enum
constants.
int is the default, and causes enum variables to be
treated as though they were of type signed int
depending on the range of the enum constants.
intlong (C++) specifies that enumerations occupy 8
bytes of storage and are represented by long,
if -q64 is specified and the range of the
enum constants exceed the limit for int.
1 will cause enum variables to be packed into 1 byte.
2 will cause enum variables to be packed into 2 bytes.
4 will cause enum variables to be packed into 4 bytes.

VisualAge C++, Version 5.5 for AIX 5L for IA-64, Beta 3 Release
Usage:
xlC [ option | inputfile ]...
xlc [ option | inputfile ]...
cc [ option | inputfile ]...
c89 [ option | inputfile ]...
xlC_r [ option | inputfile ]...
xlc_r [ option | inputfile ]...
cc_r [ option | inputfile ]...
xlC_r4 [ option | inputfile ]...
xlc_r4 [ option | inputfile ]...
cc_r4 [ option | inputfile ]...
Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,
where <key> selects the file lib<key>.a.

-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p <Currently not supported>
Generate profiling support code. Same as -qprofile=p.
-pg <Currently not supported>
Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.
-Q (C++) Turns on inlining.
-Q! (C++) Turns off inlining.
-Q<x>, -qinline<x>
(C) Inline all appropriate functions where x can be
one of the following:
! Not inline any function (equivalent to -qnoinline)
=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>
+<nm> Attempt to inline function listed by names
in <nm>.
-r Produce the output file without linking any library.

where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor
m = 'munch' utility (C++)
f = C++ name demangler utility (C++)
<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.
-w Suppress informational, language-level, and
warning messages.
-W<x,y> Give the options <y> to the compiler program <x>
where x can be one or more of the following:
<p,c,b,i,a,l,I,m,f>

2. Keyword options:
Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand
code inline.

until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).

dollar Allow '$' as an identifier character
flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.
fold Specifies that constant floating-point expressions
are to be evaluated at compile time.

you use "-g" and the symbolic debugger.
heapdebug <Currently not supported>
Enables debug versions of memory management functions.
idirfirst Specify the search order for files included with
the #include "file_name" directive. Use -qidirfirst

is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.
list Produce an object listing; output goes to .lst file.

"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the
source listing, if the SOURCE option is in effect.

srcmsg Reconstruct source lines in error along with the
diagnostic messages in the stderr file.
statsym Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the
virtual function table for a class where the first
non-inline virtual member function is declared. If
-qnovftable is specified, then no virtual function tables
are produced.

VisualAge C++, Version 5.5 for AIX 5L for IA-64, Beta 3 Release
Usage:
xlC [ option | inputfile ]...
xlc [ option | inputfile ]...
cc [ option | inputfile ]...
c89 [ option | inputfile ]...

xlc_r [ option | inputfile ]...
cc_r [ option | inputfile ]...
xlC_r4 [ option | inputfile ]...
xlc_r4 [ option | inputfile ]...
cc_r4 [ option | inputfile ]...
Description:
The xlC and related commands compile C and C++ source files.
They also processes assembler source files and object files. Unless the
-c option is specified, xlC calls the linkage editor to produce a
single object file. Input files may be any of the following:
1. file name with .C suffix: C++ source file
2. file name with .i suffix: preprocessed C or C++ source file
3. file name with .c suffix: C source file
4. file name with .o suffix: object file for ld command
5. file name with .s suffix: assembler source file
6. file name with .so suffix: shared object file
Options:
Options can be flag options or keyword options:
1. Flag options:
-# Display language processing commands but do
not invoke them; output goes to stdout.
-+ Treat .c files as C++ source code.
-bdynamic, -bstatic
Determines which types of library files are searched by
the linkage editor.
-B<prefix>
Construct alternate compiler/assembler/linkage editor
program names. <prefix> is added to the beginning of
the standard program names.
-c Do not send object files to the linkage editor.
-C Write comments to output when doing preprocessing,
used with -E and -P.
-D<name>[=<def>]
Define <name> as in #define directive. If <def> is
not specified, 1 is assumed.
-E Preprocess but do not compile; output goes to stdout
-f<filename>
Passes to the linkage editor the filename of a file
containing a list of input files to be processed.
-F<x>[:<stanza>]
Use alternate configuration file <x> with optional
<stanza>. If <stanza> is not specified, the assumed stanza
is the name of the command used to invoke the compiler.
-g Produce information for the debugger.
-G Tells the linkage editor to create a dynamic library.
-I<dir> Search in directory <dir> for include files that
do not start with an absolute path.
-l<key> Search the specified library file,

-ma Generate inline calls to the "alloca" function as if
"#pragma alloca" directives were in the source file.
-M Generate information to be included in a "make"
description file; output goes to .u file.
-o<name> Name the executable file <name> instead of a.out.
When used with the -c option and one source file,
name the object file <name> instead of filename.o.
If <name> is the name of a directory, files generated by
the compiler will be placed into that directory.
-O Optimize generated code.
-O2 Same as -O.
-O3 Perform some memory and compile time intensive
optimizations in addition to those executed with -O2.
The -O3 specific optimizations have the potential to
alter the semantics of a user's program.
The compiler guards against these optimizations at -O2
and the option -qstrict is provided at -O3 to turn off
these aggressive optimizations.
-O4 <Currently not supported>
(C) Equivalent to -O3 -qipa with automatic generation of
architecture and tuning option ideal for that platform.
-O5 <Currently not supported>
(C) Equivalent to -O3 -qipa=level=2 with automatic
generation of architecture and tuning option ideal for
that platform.
-p <Currently not supported>
Generate profiling support code. Same as -qprofile=p.
-pg <Currently not supported>
Generate profiling support code including BSD
profiling support. Same as -qprofile=pg.
-P Preprocess but do not compile; output goes to .i file.

=<lc> Inline if number of source statement in
function is less than the number specified
in <lc>.
-<nm> Not inline function listed by names in <nm>

where x can be one or more of the following:
p = preprocessor
c = compiler frontend
b = compiler backend
i = compiler inliner
a = assembler
l = linkage editor

<Currently not supported>
I = inter-procedural analysis - compile phase.
<Currently not supported>
L = inter-procedural analysis - link phase.
-U<name> Undefine name as in #undef directive.
-v Displays language processing commands as they
are invoked by xlC; output goes to stdout.
-w Suppress informational, language-level, and
warning messages.

Keyword options are specified in one of the following ways:
-q<option>
-q<option>=<parameter>
-q<option>=<parameter>:<parameter>
where <option> is an option name and <parameter> is a
parameter value.
Keyword options with no parameters represent switches
that may be either on or off. The keyword by itself turns
the switch on, and the keyword preceded by the letters NO
turns the switch off. For example, -qLIST tells the
compiler to produce a listing and -qNOLIST tells the
compiler not to produce a listing. If an option that
represents a switch is set more than once, the compiler
uses the last setting.
Keyword option and parameter names may appear in either
UPPER CASE or lower case letters in the xlC command.
Options without parameters:
32 Selects 32-bit compiler mode. (default)
64 Selects 64-bit compiler mode.
ansialias Use type-based aliasing during optimization.
attr Produce an attribute listing containing only
referenced names; output goes to .lst file.
compact Reduce code size where possible, at the expense
of execution speed. Code size is reduced by
inhibiting optimizations that replicate or expand

until the end of the current source line, as in C++.
dbcs String literals and comments can contain DBCS
characters (same as mbcs option).

dollar Allow '$' as an identifier character
flttrap <Currently not supported>
Generate instructions to trap floating-point
exceptions.

is specified, the directories specified by the
-Idirectory option are searched before the directory
where the current file resides.
ignerrno <Currently not supported>
Tell the optimizer that the program will never
refer to or set errno. This allows additional
optimizations.
inlglue Generate fast external linkage by inlining the
code (pointer glue code) necessary at calls
via a function pointer and calls to external
procedures.
libansi Assumes that all functions with the name of an
ANSI C library functions are in fact the system functions.
linedebug Generates abbreviated line number and source file name
information for the debugger.

"file_name" and #include <file_name> directives.
If -qnostdinc is specified, the /usr/include directory
is not searched.
once Only process each include file one time.
The default is -qnoonce.
optimize Same as O and O2. Perform optimization that is the
mix between speed and size. (If -qnooptimize is
specified, it is equivalent to -qoptimize=0.)
pascal Accept and ignore the keyword 'pascal' as a
type modifier.
pdf1, pdf2 <Currently not supported>
Perform aggressive optimizations with profile
directed feedback.
phsinfo Produce compiler phase information; output goes to
stdout.
proto (C) Assert that procedure call points agree
with their declarations even if the procedure has
not been prototyped. This allows the caller to
pass floating point arguments in floating point
registers instead of general purpose registers.
ro Put string literals in read only area.
roconst Put constant values in read only area.
rwvftable <Currently not supported>
(C++) Place virtual function tables into
read/write memory.
showinc Include the source of all included files in the

persistent storage class, such as initialized and
uninitialized static variables, to the name list
(the symbol table of xcoff objects). Same as
-qsymtab=static.
strict Turns off aggresive optimizations which have the
potential to alter the semantics of a user's program.
This option also sets -qfloat=nofltint:norsqrt.
strict_induction
Turns off induction variable optimizations
that have the potential to alter the semantics of a
user's program. The default is "nostrict_induction" at
-O2 or higher and "strict_induction" otherwise.
"nostrict_induction" is recomended if your program does
not have overflows or wrap arounds of loop induction
variables.
syntaxonly Causes the compiler to perform syntax checking without
generating an object file.
tempinc (C++) Automatically generate template functions in the
"tempinc" subdirectory. Use the "notempinc" option to
suppress this behaviour.
unique (C++) Generates unique names for static
constructor/destructor file compilation units.
upconv (C) Preserves the unsigned specification when performing
integral promotions.
vftable (C++) Force virtual function tables to be generated
in this compilation unit. The default is to define the
virtual function table for a class where the first
non-inline virtual member function is declared. If

information needed for typeid operator is not
generated.
smp[=suboption[:suboption] [ ... ]] (C)
<Currently not supported>
[no]auto
Enables or disables automatic parallelization.
[no]explicit
Enables or disables explicit parallelization.
schedule=<sched_type>[=n]
Specifies what kind of scheduling algorithms
and chunking are used for loops to which no
other scheduling algorithm has been explicitly
assigned in the source code.
Valid options for <sched_type> are:
* dynamic[=n]
* guided[=n]
* static[=n]
* affinity[=n]
* runtime
For more information, see online documentation.
[no]nested_par
Enables or disables parallelization of nested
parallel constructs.
[no]rec_locks
Specifies whether recursive or regular locks
should be used to implement critical sections.
[no]omp Enables or disables strict OpenMP mode.
suppress=<msg_num>:<msg_num>...
Suppress compiler messages.
nosuppress=<msg_num>:<msg_num>...
(C++) Don't suppress compiler messages.
nosuppress
(C) Don't suppress compiler messages.
symtab=<options>
Controls symbol table.
The available options are:
unref Specifies that all typedef declarations, struct,
union, and enum type definitions are included
for processing by the debugger. Same as
-qdbxextra.
static Adds user-defined, nonexternal names that have a
persistent storage class, such as initialized
and uninitialized static variables, to the name
list (the symbol table of xcoff objects). Same
as -qstatsym.
tabsize=<size>
Changes the length of tabs in your source file.
tune=<option>
Specifies the architecture system for which the
executable program is optimized.
The available options are:
itanium Produce an object optimized for Itanium processor.
tempinc[=<directory>]
(C++) Automatically generate template functions in the
specified directory. Use the "notempinc" option
to suppress this behaviour.
tempmax=<number>
(C++) Specify the maximum number of files to be created
in the tempinc directory for each template file. The
default is 1.
unroll[=n] Allow the optimizer to unroll loops.
usepcomp[=dirname]
<Currently not supported>
Use precompiled include files. See online documentation
for details.
xref=full Produce a cross-reference listing containing all names,
whether referenced or not; output goes to .lst file.
Environment Variables
1.OBJECT_MODE changes the compilation-mode behavior, unless overridden by
configuration file or command-line options
