re PR ipa/65270 (issues with merging memory accesses from different code paths)
2015-03-09 Richard Biener <rguenther@suse.de>
PR middle-end/65270
* tree-core.h (enum operand_equal_flag): Add OEP_ADDRESS_OF.
* fold-const.c (operand_equal_p): When recursing for ADDR_EXPRs
operand set OEP_ADDRESS_OF. Clear it when recursing to non-bases
of that. When comparing dereferences compare alignment.
When comparing MEM_REFs or TARGET_MEM_REFs compare dependence info.
* gcc.dg/torture/pr65270-1.c: New testcase.
* gcc.dg/torture/pr65270-2.c: Likewise.
