Summary: The optimization to early break out of loops if all threads are dead was never fully implemented. But the PHI node analyzing is actually causing a number of problems, so remove all the extra code for it. (This does actually regress code quality in a few places because it ends up relying more heavily on phi's of i1, which we don't do a great job with. However, since it fixes real bugs in the wild, we should take this change. I have some prototype changes to improve i1 lowering in general -- not just for control flow -- which should help recover the code quality, I just need to make those changes fit for general consumption. -- Nicolai) Change-Id: I6fc6c6c8961857ac6009fcfb9f7e5e48dc23fbb1 Patch-by: Christian König <christian.koenig@amd.com> Reviewers: arsenm, rampitec, tpr Subscribers: kzhuravl, jvesely, wdng, yaxunl, dstuttard, t-tye, llvm-commits Differential Revision: https://reviews.llvm.org/D53359 llvm-svn: 345718 |
