Raw Normal View History

Revert the main portion of r31856. It was causing BranchFolding to break up CFG diamonds by banishing one of the blocks to the end of the function, which is bad for code density and branch size. This does pessimize MultiSource/Benchmarks/Ptrdist/yacr2, the benchmark cited as the reason for the change, however I've examined the code and it looks more like a case of gaming a particular branch than of being generally applicable. llvm-svn: 84803

Fix PR3274: when promoting the condition of a BRCOND node, promote from i1 all the way up to the canonical SetCC type. In order to discover an appropriate type to use, pass MVT::Other to getSetCCResultType. In order to be able to do this, change getSetCCResultType to take a type as an argument, not a value (this is also more logical). llvm-svn: 61542

CellSPU: - Fix fabs, fneg for f32 and f64. - Use BuildVectorSDNode.isConstantSplat, now that the functionality exists - Continue to improve i64 constant lowering. Lower certain special constants to the constant pool when they correspond to SPU's shufb instruction's special mask values. This avoids the overhead of performing a shuffle on a zero-filled vector just to get the special constant when the memory load suffices. llvm-svn: 67067
