[Martin Storsjö via Phabricator via llvm-commits]

mstorsjo added a comment.

This triggers failed asserts for me, with https://martin.st/temp/macroblock-reduced.c:

  $ clang -target aarch64-linux-gnu -c macroblock-reduced.c -O2
  clang: ../lib/Transforms/Scalar/IndVarSimplify.cpp:2059: bool {anonymous}::IndVarSimplify::run(llvm::Loop*): Assertion `L->isRecursivelyLCSSAForm(*DT, *LI) && "Indvars did not preserve LCSSA!"' failed.
