dim 04dc31bd5f For now, revert r287232 from upstream llvm trunk (by Daniil Fukalov): ... [SCEV] limit recursion depth of CompareSCEVComplexity Summary: CompareSCEVComplexity goes too deep (50+ on a quite a big unrolled loop) and runs almost infinite time. Added cache of "equal" SCEV pairs to earlier cutoff of further estimation. Recursion depth limit was also introduced as a parameter. Reviewers: sanjoy Subscribers: mzolotukhin, tstellarAMD, llvm-commits Differential Revision: https://reviews.llvm.org/D26389 This commit is the cause of excessive compile times on skein_block.c (and possibly other files) during kernel builds on amd64. We never saw the problematic behavior described in this upstream commit, so for now it is better to revert it. An upstream bug has been filed here: https://bugs.llvm.org/show_bug.cgi?id=32142 Reported by: mjg		2017-03-05 19:56:20 +00:00
