Output Options by Language

See the C++ list
See the F95 list

C Output Options

Option	Meaning
-#	Turns on verbose modes, showing how command options expand. Shows each component as it is invoked.
-###	Shows each component as it would be invoked, but does not actually execute it. Also shows how command options would expand.
-c	Suppresses linking with the linker and, instead, produces a .o file for each source file.
-E	Directs the CC driver to only preprocess the C++ source files, and to send the result to stdout (standard output).
-erroff	Suppresses compiler warning messages but has no effect on error messages.
-errtags	Displays the message tag for each warning message of the compiler front-end that can be suppressed with the -erroffoption or made a fatal error with the -errwarn option.
-errwarn	Causes the compiler to exit with a failure status for the given warning messages.
-G	Build a dynamic shared library instead of an executable file.
-H	Prints the path name of each include file contained in the current compilation to the standard error output.
-o	Sets the name of the output file (with the suffix .o) or the executable file.
-P	Only preprocesses source; does not compile.
-Q	Emits identification information to the output file.
-S	Compiles and generates only assembly code.
-s	Strips the symbol table from the executable file.
-v	Performs more and stricter semantic checks, and enables certain lint-like checks on the named C files.
-w	Suppresses warning messages.
-xdryrun	Shows each component as it would be invoked, but does not actually execute it. Also shows how command options would expand.
-xe	Checks only for syntax and semantic errors.
-xhelp	Displays online help for compiler options or latest readme.
-xM	Runs only the preprocessor on the named C++ programs, requesting that it generate makefile dependencies and sendthe result to the standard outputx
-xM1	Same as -xM, except that this option does not report dependencies for the /usr/include header files and it does not report dependencies for compiler-supplied header files.
-xsbfast	Creates the database for the Source Browser, but does not actually compile.
-xtime	Causes the CC driver to report execution times for the various compilation passes.

C++ Output Options

Option	Meaning
-c	Suppresses linking with the linker and, instead, produces a .o file for each source file.
-dryrun	Shows each component as it would be invoked, but does not actually execute it. Also shows how command options would expand.
-E	Directs the CC driver to only preprocess the C++ source files, and to send the result to stdout (standard output).
-erroff	Suppresses compiler warning messages but has no effect on error messages.
-errtags	Displays the message tag for each warning message of the compiler front-end that can be suppressed with the -erroffoption or made a fatal error with the -errwarn option.
-errwarn	Causes the compiler to exit with a failure status for the given warning messages.
-filt	Suppress the filtering that the C++ compiler normally applies to linker error messages.
-G	Build a dynamic shared library instead of an executable file.
-H	Prints the path name of each include file contained in the current compilation to the standard error output.
-migration	Explains where to get information about migrating source code that was built for earlier versions of the compiler.
-o	Sets the name of the output file (with the suffix .o) or the executable file.
-P	Only preprocesses source; does not compile.
-S	Compiles and generates only assembly code.
-s	Strips the symbol table from the executable file.
-verbose	Controls compiler verbosity.
+w	Identifies code that might have unintended consequences.
+w2	Emits the same warnings as +w as well as warnings about technical violations that are probably harmless, but that might reduce the maximum portability of your program.
-w	Suppresses warning messages.
-xdumpmacros	Shows how macros are behaving in your program.
-xe	Checks only for syntax and semantic errors.
-xhelp	Displays online help for compiler options or latest readme.
-xM	Runs only the preprocessor on the named C++ programs, requesting that it generate makefile dependencies and sendthe result to the standard outputx
-xM1	Same as -xM, except that this option does not report dependencies for the /usr/include header files and it does not report dependencies for compiler-supplied header files.
-xtime	Causes the CC driver to report execution times for the various compilation passes.
-xwe	Converts all warnings to errors by returning non-zero exit status.
-z	Link editor option.
