| Option | Language | Meaning |
|---|---|---|
| -# | C | Turns on verbose modes, showing how command options expand. Shows each component as it is invoked. |
| -### | C | Shows each component as it would be invoked, but does not actually execute it. Also shows how command options would expand. |
| -c | C C++ F95 | Suppresses linking with the linker and, instead, produces a .o file for each source file. |
| -dryrun | C++ F95 | Shows each component as it would be invoked, but does not actually execute it. Also shows how command options would expand. |
| -E | C C++ | Directs the CC driver to only preprocess the C++ source files, and to send the result to stdout (standard output). |
| -erroff | C C++ F95 | Suppresses compiler warning messages but has no effect on error messages. |
| -errtags | C C++ F95 | 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 | C C++ F95 | Causes the compiler to exit with a failure status for the given warning messages. |
| -filt | C++ | Suppress the filtering that the C++ compiler normally applies to linker error messages. |
| -G | C C++ F95 | Build a dynamic shared library instead of an executable file. |
| -H | C C++ | Prints the path name of each include file contained in the current compilation to the standard error output. |
| -migration | C++ | Explains where to get information about migrating source code that was built for earlier versions of the compiler. |
| -o | C C++ F95 | Sets the name of the output file (with the suffix .o) or the executable file. |
| -P | C C++ | Only preprocesses source; does not compile. |
| -Q | C | Emits identification information to the output file. |
| -S | C C++ F95 | Compiles and generates only assembly code. |
| -s | C C++ F95 | Strips the symbol table from the executable file. |
| -v | F95 | Verbose mode - shows compilation details. |
| -v | C | Performs more and stricter semantic checks, and enables certain lint-like checks on the named C files. |
| -verbose | C++ | Controls compiler verbosity. |
| +w | C++ | Identifies code that might have unintended consequences. |
| +w2 | C++ | 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 | C C++ F95 | Suppresses warning messages. |
| -Xlist | F95 | Finds potential programming bugs. Invokes an extra compiler pass to check for consistency in calls and common across the global program. |
| -xdryrun | C | Shows each component as it would be invoked, but does not actually execute it. Also shows how command options would expand. |
| -xdumpmacros | C++ | Shows how macros are behaving in your program. |
| -xe | C C++ | Checks only for syntax and semantic errors. |
| -xhelp | C C++ F95 | Displays online help for compiler options or latest readme. |
| -xM1 | C C++ | 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. |
| -xM | C C++ | Runs only the preprocessor on the named C++ programs, requesting that it generate makefile dependencies and send the result to the standard outputx |
| -xsbfast | C | Creates the database for the Source Browser, but does not actually compile. |
| -xtime | C C++ F95 | Causes the CC driver to report execution times for the various compilation passes. |
| -xwe | C++ | Converts all warnings to errors by returning non-zero exit status. |
| -z | C++ | Link editor option. |
