[PATCH] D112932: Use llvm.is_fpclass to implement FP classification functions

[Matt Arsenault via Phabricator via cfe-commits]

arsenm added inline comments.


================
Comment at: clang/lib/CodeGen/CGBuiltin.cpp:2185-2187
+  auto TestV = llvm::ConstantInt::get(CGF->Int32Ty, Test);
+  Function *F = CGF->CGM.getIntrinsic(Intrinsic::is_fpclass, V->getType());
+  return CGF->Builder.CreateCall(F, {V, TestV});
----------------
Might as well put this in IRBuilder
