[PATCH] D45173: [InstCombine] Recognize idioms for ctpop and ctlz

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

Would a change like the one in PassManagerBuilder.cpp be acceptable?  There may be some work to make sure that the pre-existing components of the aggressive instcombine still apply, but I'm wondering if this direction is something we could agree on.
