re PR tree-optimization/68583 (Missed if-conversion)
2015-12-09 Richard Biener <rguenther@suse.de>
PR tree-optimization/68583
* tree-if-conv.c (if_convertible_phi_p): Drop
flag_tree_loop_if_convert_stores check in favor of the
existing any_mask_load_store check.
(insert_gimplified_predicates): Likewise.
(combine_blocks): Likewise.
(tree_if_conversion): Likewise.
(ifcvt_memrefs_wont_trap): Properly check
flag_tree_loop_if_convert_stores in all places that can end
up introducing store-data-races.
(if_convertible_gimple_assign_stmt_p): Remove restriction
on flag_tree_loop_if_convert_stores for stores we can if-convert
without introducing store-data-races. Force versioning for
all if-converted stores.
* gcc.dg/tree-ssa/ifc-pr68583.c: New testcase.
* gcc.dg/vect/vect-72.c: Adjust.
* gcc.dg/vect/vect-cselim-2.c: Likewise.
* gcc.dg/vect/vect-strided-store-a-u8-i2.c: Likewise.
