Chandler Carruth 27abbcdaaa [x86] Teach the X86 backend to print shuffle comments for PSHUFB instructions which happen to have a constant mask. Currently, this only handles a very narrow set of cases, but those happen to be the cases that I care about for testing shuffles sanely. This is a bit trickier than other shuffle instructions because we're decoding constants out of the constant pool. The current MC layer makes it completely impossible to inspect a constant pool entry, so we have to do it at the MI level and attach the comment to the streamer on its way out. So no joy for disassembling, but it does make test cases and asm dumps much nicer. Sorry for no test cases, but it didn't really seem that valuable to go trolling through existing old test cases and updating them. I'll have lots of testing of this in the upcoming patch for SSSE3 emission in the new vector shuffle lowering code paths. llvm-svn: 213986		2014-07-25 23:47:11 +00:00
