Sanjay Patel fb26cf0017 Fix program crashes due to alignment exceptions generated for SSE memop instructions (PR22371). ... r224330 introduced a bug by misinterpreting the "FeatureVectorUAMem" bit. The commit log says that change did not affect anything, but that's not correct. That change allowed SSE instructions to have unaligned mem operands folded into math ops, and that's not allowed in the default specification for any SSE variant. The bug is exposed when compiling for an AVX-capable CPU that had this feature flag but without enabling AVX codegen. Another mistake in r224330 was not adding the feature flag to all AVX CPUs; the AMD chips were excluded. This is part of the fix for PR22371 ( http://llvm.org/bugs/show_bug.cgi?id=22371 ). This feature bit is SSE-specific, so I've renamed it to "FeatureSSEUnalignedMem". Changed the existing test case for the feature bit to reflect the new name and renamed the test file itself to better reflect the feature. Added runs to fold-vex.ll to check for the failing codegen. Note that the feature bit is not set by default on any CPU because it may require a configuration register setting to enable the enhanced unaligned behavior. llvm-svn: 227983		2015-02-03 17:13:04 +00:00
