[PATCH] D83047: [LiveDebugValues] 2/4 Add instruction-referencing LiveDebugValues implementation

[Jeremy Morse via Phabricator via llvm-commits]

jmorse added a comment.

NB: in D83054 <https://reviews.llvm.org/D83054> I've added livedebugvalues_many_loop_heads.mir which contains a worked example (aka pathological input) that exercises the lattice-descent code for machine value numbers. It's definitely the ugliest part.
