Here is an updated patch that folds in all the feedback I've gotten on this so far, and fixes the arg splitting bug in nested spec functions. * gcc.c (The Specs Language): Document spec functions. (static_spec_functions, lookup_spec_function) (eval_spec_function, handle_spec_function) (if_exists_spec_function, alloc_args): New. (execute): Abort if processing_spec_function is true. (do_spec_1): Hand off spec to handle_spec_function if %: is encountered. If processing_spec_function is true, end any pending argument when the end of the string is reached. (main): Use alloc_args to allocate the initial argument vector. * gcc.h (struct spec_function): New. (lang_specific_lookup_spec_function): New prototype * config/netbsd-elf.h (STARTFILE_SPEC): Add if-exists(crti%O%s). (ENDFILE_SPEC): Add if-exists(crtn%O%s). * config/alpha/netbsd.h (ENDFILE_SPEC): Likewise. * doc/invoke.texi: Document spec functions. * doc/tm.texi: Document EXTRA_SPEC_FUNCTIONS. * cppspec.c (lang_specific_lookup_spec_function): New. * gccspec.c (lang_specific_lookup_spec_function): New. * g++spec.c (lang_specific_lookup_spec_function): New. * g77spec.c (lang_specific_lookup_spec_function): New. * jvspec.c (lang_specific_lookup_spec_function): New. -- -- Jason R.
