[PATCH] D120580: [bugpoint] construct a plausible TargetMachine for simplifyCFG

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope added a comment.

Sorry, I don't know much about bugpoint to understand if this is feasible or not. I doubt that the CFG simplification done by bugpoint really need to take target specific costs etc into account? We just want to simplify the flow, but not optimize it for a given target, right?
I don't find the motivation that strong and there are no test cases etc included that show any gains.

But maybe you could try to find some reviewers that know more about llvm-bugpoint. Unfortunately it seems like there haven't been many functional commits to the tool lately (looking at git log), so I do not really have any immediate candidates to add as reviewers.
