[PATCH] D28236: InstCombine: Fold cos(-x) -> cos(x)

[Davide Italiano via Phabricator via llvm-commits]

davide added inline comments.


================
Comment at: lib/Transforms/InstCombine/InstCombineCalls.cpp:1641
+  case Intrinsic::cos:
+  case Intrinsic::amdgcn_cos: {
+    Value *SrcSrc;
----------------
While here, I also noticed the `amdgcn_cos` is not documented in `LangRef`, maybe it could be (or somewhere else)
