Craig Topper	72b41227d8	Merge isSHUFPMask and isCommutedSHUFPMask into single function that can do both. Do the same for the 256-bit version. Use loops to reduce size of isVSHUFPYMask. Fix test cases that were incorrectly passing due to isCommutedSHUFPMask not checking for the vector being 128-bit. This caused some 256-bit shuffles to be incorrectly commuted. ... llvm-svn: 145921	2011-12-06 04:59:07 +00:00
Bruno Cardoso Lopes	2d100ca13c	The VPERM2F128 is a AVX instruction which permutes between two 256-bit ... vectors. It operates on 128-bit elements instead of regular scalar types. Recognize shuffles that are suitable for VPERM2F128 and teach the x86 legalizer how to handle them. llvm-svn: 137519	2011-08-12 21:48:26 +00:00
