Chandler Carruth 48593d7934 [x86] Just unilaterally prefer SSSE3-style PSHUFB lowerings over clever ... use of PACKUS. It's cleaner that way. I looked at implementing clever combine-based folding of PACKUS chains into PSHUFB but it is quite hard and doesn't seem likely to be worth it. The most annoying part would be detecting that the correct masking had been done to use PACKUS-style instructions as a blend operation rather than there being any saturating as is indicated by its name. We generate really nice code for what few test cases I've come up with that aren't completely contrived for this by just directly prefering PSHUFB and so let's go with that strategy for now. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214707 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-04 10:17:35 +00:00
