[PATCH] D71164: [InstCombine] Fix infinite loop due to bitcast <-> phi transforms

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

I've updated the patch to directly perform the load combine now. I believe the store case shouldn't exhibit the same issue, as the bitcast is cannot be a phi operand there. I've also added the new looping testcase and `-instcombine-infinite-loop-threshold=2` to make sure that the combine runs through in one iteration.
