Subject: tree-inline.c (optimize_inline_calls): Schedule cleanups only if we inlined something.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5d7b099c0a22ecc85218a99ef0df58b9240fdd4e;p=gcc.git

tree-inline.c (optimize_inline_calls): Schedule cleanups only if we inlined something.

2010-09-22  Richard Guenther  <rguenther@suse.de>

	* tree-inline.c (optimize_inline_calls): Schedule cleanups
	only if we inlined something.  Block compaction and conditional
	folding are done by cfg cleanup.  Schedule update-address-taken.
	(tree_function_versioning): Remove redundant call to number_blocks.
	* tree-optimize.c (execute_cleanup_cfg_post_optimizing): Conditional
	folding is done by cfg cleanup.
	* passes.c (init_optimization_passes): Remove update-address-taken
	pass after IPA inlining.
