The stack realignment code was fixed to work when there is stack realignment and a dynamic alloca is present so this shouldn't cause correctness issues anymore. Note that this also enables generation of AVX instructions for memset under the assumptions: - Unaligned loads/stores are always fast on CPUs supporting AVX - AVX is not slower than SSE We may need some tweaked heuristics if one of those assumptions turns out not to be true. Effectively reverts r58317. Part of PR2962. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167967 91177308-0d34-0410-b5e6-96231b3b80d8
