X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c05c1b41d370b14bc94421f138d13e76831253d1;p=thirdparty%2Fgcc.git

[PATCH] [5/n] Fix minor SSA_NAME leaks

	* value-prof.c (gimple_ic): Add missing calls to unlink_stmt_vdef
	and release_ssa_name in two places.
	(gimple_stringop_fixed_value): Similarly.
