Sanjay Patel ab4ad4f98e Optimize merging of scalar loads for 32-byte vectors [X86, AVX] ... Fix the poor codegen seen in PR21710 ( http://llvm.org/bugs/show_bug.cgi?id=21710 ). Before we crack 32-byte build vectors into smaller chunks (and then subsequently glue them back together), we should look for the easy case where we can just load all elements in a single op. An example of the codegen change is: From: vmovss 16(%rdi), %xmm1 vmovups (%rdi), %xmm0 vinsertps $16, 20(%rdi), %xmm1, %xmm1 vinsertps $32, 24(%rdi), %xmm1, %xmm1 vinsertps $48, 28(%rdi), %xmm1, %xmm1 vinsertf128 $1, %xmm1, %ymm0, %ymm0 retq To: vmovups (%rdi), %ymm0 retq Differential Revision: http://reviews.llvm.org/D6536 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223518 91177308-0d34-0410-b5e6-96231b3b80d8		2014-12-05 21:28:14 +00:00
