- # gcc(1) completion

- # The only unusual feature is that we don't parse "gcc --help -v" output
- # directly, because that would include the options of all the other backend
- # tools (linker, assembler, preprocessor, etc) without any indication that
- # you cannot feed such options to the gcc driver directly. (For example, the
- # linker takes a -z option, but you must type -Wl,-z for gcc.) Instead, we
- # ask the driver ("g++") for the name of the compiler ("cc1"), and parse the
- # --help output of the compiler.
