Sanjay Patel 01403f9711 allow branch weight metadata on select instructions (PR26636) ... As noted in: https://llvm.org/bugs/show_bug.cgi?id=26636 This doesn't accomplish anything on its own. It's the first step towards preserving and using branch weights with selects. The next step would be to make sure we're propagating the info in all of the other places where we create selects (SimplifyCFG, InstCombine, etc). I don't think there's an easy fix to make this happen; we have to look at each transform individually to determine how to correctly propagate the weights. Along with that step, we need to then use the weights when making subsequent transform decisions such as discussed in http://reviews.llvm.org/D16836. The inliner test is independent but closely related. It verifies that metadata is preserved when both branches and selects are cloned.
