Function Documentation

static void add_input_filename ( )

static

Handle FILENAME from the command line.   

References in_fnames, and num_in_fnames.

Referenced by read_cmdline_options().

static void complain_wrong_lang ( const struct cl_decoded_option *  decoded, unsigned int  lang_mask  )

static

Complain that switch DECODED does not apply to this front end (mask
   LANG_MASK).   

References cl_lang_count, cl_options, lang_hooks::complain_wrong_lang_p, error(), cl_option::flags, free(), cl_decoded_option::opt_index, option(), cl_decoded_option::orig_option_with_args_text, warning(), and write_langs().

void decode_cmdline_options_to_array_default_mask	(	unsigned int	argc,
		const char **	argv,
		struct cl_decoded_option **	decoded_options,
		unsigned int *	decoded_options_count
	)

Decode command-line options to an array, like
   decode_cmdline_options_to_array and with the same arguments but
   using the default lang_mask.   

References decode_cmdline_options_to_array(), and initial_lang_mask.

		struct gcc_options *	opts_set,
		struct cl_decoded_option *	decoded_options,
		unsigned int	decoded_options_count,
		location_t	loc,
		diagnostic_context *	dc
	)

Parse command line options and set default flag values.  Do minimal
   options processing.  The decoded options are in *DECODED_OPTIONS
   and *DECODED_OPTIONS_COUNT; settings go in OPTS, OPTS_SET and DC;
   the options are located at LOC.

static void dump_remap_tree_vectorizer_verbose ( )

static

Handle -ftree-vectorizer-verbose=ARG by remapping it to -fopt-info.
   It remaps the old verbosity values as following:

   REPORT_NONE ==> No dump is output
   REPORT_VECTORIZED_LOCATIONS ==> "-optimized"
   REPORT_UNVECTORIZED_LOCATIONS ==> "-missed"

   Any higher verbosity levels get mapped to "-all" flags.

void handle_common_deferred_options

(

void

)

Process common options that have been deferred until after the
   handlers have been called for all options.

   handle_option.

static void postpone_unknown_option_warning ( )

static

Buffer the unknown option described by the string OPT.  Currently,
   we only complain about unknown -Wno-* options if they may have
   prevented a diagnostic. Otherwise, we just ignore them.  Note that
   if we do complain, it is only as a warning, not an error; passing
   the compiler an unrecognised -Wno-* option should never change
   whether the compilation succeeds or fails.

void print_ignored_options

(

void

)

Produce a warning for each option previously buffered.

static

Handle the vector of command line options (located at LOC), storing
   the results of processing DECODED_OPTIONS and DECODED_OPTIONS_COUNT
   in OPTS and OPTS_SET and using DC for diagnostic state.  LANG_MASK
   contains has a single bit set representing the current language.
   HANDLERS describes what functions to call for the options.
