\--help=\{common|optimizers|params|target|warnings|\[^\]\{joined|separate|undocumented\}\}\[,...\]  
Display specific types of command line options  
(Use '-v --help' to display command line options of sub-processes)  
\--version Display compiler version information  
\-dumpspecs Display all of the built in spec strings  
\-dumpversion Display the version of the compiler  
\-dumpmachine Display the compiler's target processor  
\-print-search-dirs Display the directories in the compiler's search path  
\-print-libgcc-file-name Display the name of the compiler's companion library  
\-print-file-name=<lib> Display the full path to library <lib>  
\-print-prog-name=<prog> Display the full path to compiler component <prog>  
\-print-multiarch Display the target's normalized GNU triplet, used as  
a component in the library path  
\-print-multi-directory Display the root directory for versions of libgcc  
\-print-multi-lib Display the mapping between command line options and  
multiple library search directories  
\-print-multi-os-directory Display the relative path to OS libraries  
\-print-sysroot Display the target libraries directory  
\-print-sysroot-headers-suffix Display the sysroot suffix used to find headers  
\-Wa,<options> Pass comma-separated <options> on to the assembler  
\-Wp,<options> Pass comma-separated <options> on to the preprocessor  
\-Wl,<options> Pass comma-separated <options> on to the linker  
\-Xassembler <arg> Pass <arg> on to the assembler  
\-Xpreprocessor <arg> Pass <arg> on to the preprocessor  
\-Xlinker <arg> Pass <arg> on to the linker  
\-save-temps Do not delete intermediate files  
\-save-temps=<arg> Do not delete intermediate files  
\-no-canonical-prefixes Do not canonicalize paths when building relative  
prefixes to other gcc components  
\-pipe Use pipes rather than intermediate files  
\-time Time the execution of each subprocess  
\-specs=<file> Override built-in specs with the contents of <file>  
\-std=<standard> Assume that the input sources are for <standard>  
\--sysroot=<directory> Use <directory> as the root directory for headers  
and libraries  
\-B <directory> Add <directory> to the compiler's search paths  
\-v Display the programs invoked by the compiler  
\-\#\#\# Like -v but options quoted and commands not executed  
\-E Preprocess only; do not compile, assemble or link  
\-S Compile only; do not assemble or link  
\-c Compile and assemble, but do not link  
\-o <file> Place the output into <file>  
\-pie Create a position independent executable  
\-shared Create a shared library  
\-x <language> Specify the language of the following input files  
Permissible languages include: c c++ assembler none  
'none' means revert to the default behavior of  
guessing the language based on the file's extension  
  
Options starting with -g, -f, -m, -O, -W, or --param are automatically  
passed on to the various sub-processes invoked by gcc. In order to pass  
other options on to these processes the -W<letter> options must be used.
