[PATCH] D93838: [SCCP] Add Function Specialization pass

[Jon Chesterfield via Phabricator via llvm-commits]

JonChesterfield added a comment.

Getting the heuristics right will be difficult here.

There are a bunch of places in the openmp runtime where function pointers are passed to big functions. Manually tagging those arguments with an attribute in exchange for guaranteed specialisation when they're constant would be high value, even without any heuristics to automate the decision.
