Filipe Cabecinhas c5f611404c Convert some X86 blendv* intrinsics into IR. ... Summary: Implemented an InstCombine transformation that takes a blendv* intrinsic call and translates it into an IR select, if the mask is constant. This will eventually get lowered into blends with immediates if possible, or pblendvb (with an option to further optimize if we can transform the pblendvb into a blend+immediate instruction, depending on the selector). It will also enable optimizations by the IR passes, which give up on sight of the intrinsic. Both the transformation and the lowering of its result to asm got shiny new tests. The transformation is a bit convoluted because of blendvp[sd]'s definition: Its mask is a floating point value! This forces us to convert it and get the highest bit. I suppose this happened because the mask has type __m128 in Intel's intrinsic and v4sf (for blendps) in gcc's builtin. I will send an email to llvm-dev to discuss if we want to change this or not.

Feature
FileCheck
Instrumentation	[asan] properly instrument memory accesses that have small alignment (smaller than min(8,size)) by making two checks instead of one. This may slowdown some cases, e.g. long long on 32-bit or wide loads produced after loop unrolling. The benefit is higher sencitivity.	2014-05-23 11:52:07 +00:00
