[PATCH] D93857: Revert "[InstCombine] Hoist xor-by-constant from xor-by-value"

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

It would be best to have the reproducer beforehand.
Usually it should be fine to just dump the whole module's IR
in `InstCombinerImpl::run()` as the first thing in that loop,
save the IR that is clearly stuck within the inf combine loop,
and feed it to `llvm-reduce`..
