Author: rguenth Date: Thu Jul 8 11:38:43 2010 New Revision: 161950 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=161950 Log: 2010-07-08 Richard Guenther <rguent...@suse.de> PR tree-optimization/44831 * tree-ssa-phiprop.c (phiprop_insert_phi): Properly build a MEM_REF preserving TBAA info of the original dereference. Dereference the original pointer if the address is not invariant. (propagate_with_phi): Fixup type checks wrt MEM_REFs. Require at least one invariant address that we are going to dereference. * gcc.c-torture/compile/pr44831.c: New testcase. * gcc.dg/tree-ssa/pr21463.c: Adjust.
