any phase.

◆ dump_start()

int gcc::dump_manager::dump_start	(	int	phase,
		dump_flags_t *	flag_ptr )

Start a dump for PHASE. Store user-supplied dump flags in
*FLAG_PTR.  Return the number of streams opened.  Set globals
DUMP_FILE, and ALT_DUMP_FILE to point to the opened streams, and
set dump_flags appropriately for both pass dump stream and
-fopt-info stream.

private

Parse ARG as a dump switch.  Return nonzero if it is, and store the
relevant details in the dump_files array.

◆ get_dump_file_info()

struct dump_file_info * gcc::dump_manager::get_dump_file_info ( int phase ) const

◆ get_dump_file_info_by_switch()

struct dump_file_info * gcc::dump_manager::get_dump_file_info_by_switch ( const char * swtch ) const

or return NULL if no such dump_file_info exists.

References ggc_alloc(), i, and NULL.

◆ get_dump_file_name() [1/2]

char * gcc::dump_manager::get_dump_file_name	(	int	phase,
		int	part = -1 ) const

The caller is responsible for calling free on the returned
buffer.
If the dump is not enabled, returns NULL.

◆ get_dump_file_name() [2/2]

char * gcc::dump_manager::get_dump_file_name	(	struct dump_file_info *	dfi,
		int	part = -1 ) const

Return the name of the dump file for the given dump_file_info.
The caller is responsible for calling free on the returned
buffer.
If the dump is not enabled, returns NULL.

int gcc::dump_manager::opt_info_enable_passes	(	optgroup_flags_t	optgroup_flags,
		dump_flags_t	flags,
		const char *	filename )

private

Enable -fopt-info dumps on all dump files matching OPTGROUP_FLAGS.
Enable dumps with FLAGS on FILENAME.  Return the number of enabled
dumps.

References dump_files, ggc_alloc(), i, TDI_end, and TDI_none.

◆ register_dumps()

void gcc::dump_manager::register_dumps ( )

Allow languages and middle-end to register their dumps before the
optimization passes.

References dump_files, FIRST_ME_AUTO_NUMBERED_DUMP, gcc_assert, dump_file_info::num, lang_hooks::register_dumps, TDI_gimple, TDI_nested, and TDI_original.

Referenced by general_init().

◆ register_pass()

void gcc::dump_manager::register_pass ( opt_pass * pass )

Handle -fdump-* and -fopt-info for a pass added after
command-line options are parsed (those from plugins and
those from backends).

Because the registration of plugin/backend passes happens after the
command-line options are parsed, the options that specify single
pass dumping (e.g. -fdump-tree-PASSNAME) cannot be used for new
passes. Therefore we currently can only enable dumping of
new passes when the 'dump-all' flags (e.g. -fdump-tree-all)
are specified.  This is done here.

Similarly, the saved -fopt-info options are wired up to the new pass.

◆ update_dfi_for_opt_info()

bool gcc::dump_manager::update_dfi_for_opt_info ( dump_file_info * dfi ) const

private

Use the saved -fopt-info options to update DFI.
Return true if the dump is enabled.
