[PATCH] D65457: [InstCombine] Optimize div/ldiv/lldiv

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

What targets does the divl and divll code work for? Definitely doesn't work for arm on linux or i386 on linux. But those are the only ones I checked.

Would it be better to just recognize this as a builtin in clang and just emit the IR instructions?
