[PATCH] D150375: [FuncSpec] Replace LoopInfo with BlockFrequencyInfo.

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope added a comment.

Beware: The reproducer provided by uabelho is reduced, but it is a bit ugly. I spent some time trying to clean it up, but even when using valgrind/asan it is hard to get a nice and small reproducer (e.g. that would show an incorrect PDT when using  `print<postdomtree>`). I even ended up in a situation when renaming the labels used in the IR suddenly made the reproducer no longer crashing. So the reproducer seem to be a bit sensitive to how things end up in memory(?).
