| 2016-08-03 | Adding -verify-machineinstrs option to PowerPC tests | Ehsan Amiri | |
| Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277624 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
| 2015-07-29 | [PPC] Fix PR24216: Don't generate splat for misaligned shuffle mask | Bill Schmidt | |
| Given certain shuffle-vector masks, LLVM emits splat instructions which splat the wrong bytes from the source register. The issue is that the function PPC::isSplatShuffleMask() in PPCISelLowering.cpp does not ensure that the splat pattern found is requesting bytes that are aligned on an EltSize boundary. This patch detects this situation as not a valid splat mask, resulting in a permute being generated instead of a splat. Patch and test case by Tyler Kenney, cleaned up a bit by me. This is a simple bug fix that would be good to incorporate into 3.7. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@243519 91177308-0d34-0410-b5e6-96231b3b80d8 | |||
