[PATCH] D109958: [LoopFlatten] Enable it by default

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I think clang/test/Profile/misexpect-switch-only-default-case.c may get a failure with -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON which enables verify-scev if this pass is enabled by default.

I think the pass needs to call SE->forgetLoopDispositions() when it flattens loops. I don't know exactly what LoopDispositions are in SCEV so hopefully someone else can take a look.
