Manman Ren	16649b0107	TBAA: remove !tbaa from testing cases if not used. This will make it easier to turn on struct-path aware TBAA since the metadata format will change. llvm-svn: 180935	2013-05-02 18:11:35 +00:00
Evan Cheng	58a95f0c8a	Avoid creating a cycle when folding load / op with flag / store. PR11451474. rdar://11451474 llvm-svn: 156896	2012-05-16 01:54:27 +00:00
Joel Jones	68d59e8a90	For X86, change load/dec-or-inc/store into dec-or-inc, respectively. This is a code change to add support for changing instruction sequences of the form: load inc/dec of 8/16/32/64 bits store into the appropriate X86 inc/dec through memory instruction: inc[qlwb] / dec[qlwb] The checks that were in X86DAGToDAGISel::Select(SDNode *Node)>>ISD::STORE have been extracted to isLoadIncOrDecStore and reworked to use the better named wrappers for getOperand(unsigned) (e.g. getOffset()) and replaced Chain.getNode() with LoadNode. The comments have also been expanded. llvm-svn: 153635	2012-03-29 05:45:48 +00:00
