r181250 - in /trunk/gcc: ChangeLog testsuite/Ch...


Author: jakub
Date: Thu Nov 10 08:29:52 2011
New Revision: 181250

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=181250
Log:
	PR tree-optimization/51000
	* tree-vect-patterns.c (vect_recog_bool_pattern): If adding
	a pattern stmt for a bool store, adjust DR_STMT too.
	Don't handle bool conversions to single bit precision lhs.
	* tree-vect-stmts.c (vect_remove_stores): If next is a pattern
	stmt, remove its related stmt and free its stmt_vinfo.
	(free_stmt_vec_info): Free also pattern stmt's vinfo and
	pattern def stmt's vinfo.
	* tree-vect-loop.c (destroy_loop_vec_info): Don't try to
	free pattern stmt's vinfo here.
	(vect_transform_loop): When calling vect_remove_stores,
	do gsi_next first and don't call gsi_remove.  If not strided
	store, free stmt vinfo for gsi_stmt (si) rather than stmt.

	* gcc.dg/vect/pr51000.c: New test.
