llvm/test/CodeGen/X86/vector-gep.ll: Appease to add -mtriple=i686-linux. This doesn't pass if stack alignment is not 16, like cygming, *bsd. llvm-svn: 212334

[x86] Revert r212324 which was too aggressive w.r.t. allowing undef lanes in vector splats. The core problem here is that undef lanes can't *unilaterally* be considered to contribute to splats. Their handling needs to be more cautious. There is also a reported failure of the nightly testers (thanks Tobias!) that may well stem from the same core issue. I'm going to fix this theoretical issue, factor the APIs a bit better, and then verify that I don't see anything bad with Tobias's reduction from the test suite before recommitting. Original commit message for r212324: [x86] Generalize BuildVectorSDNode::getConstantSplatValue to work for any constant, constant FP, or undef splat and to tolerate any undef lanes in a splat, then replace all uses of isSplatVector in X86's lowering with it. This fixes issues where undef lanes in an otherwise splat vector would prevent the splat logic from firing. It is a touch more awkward to use this interface, but it is much more accurate. Suggestions for better interface structuring welcome. With this fix, the code generated with the widening legalization strategy for widen_cast-4.ll is *dramatically* improved as the special lowering strategies for a v16i8 SRA kick in even though the high lanes are undef. We also get a slightly different choice for broadcasting an aligned memory location, and use vpshufd instead of vbroadcastss. This looks like a minor win for pipelining and domain crossing, but a minor loss for the number of micro-ops. I suspect its a wash, but folks can easily tweak the lowering if they want. llvm-svn: 212475

Fix a bug in the code that builds SDNodes from vector GEPs. When the GEP index is a vector of pointers, the code that calculated the size of the element started from the vector type, and not the contained pointer type. As a result, instead of looking at the data element pointed by the vector, this code used the size of the vector. This works for 32bit members (on 32bit systems), but not for other types. Added code to peel the vector type and added a test. llvm-svn: 151626
