Thank you for the patch -- can you add some test cases?



================
Comment at: clang/lib/Sema/SemaChecking.cpp:5835-5836
+            "is the only expected cast here");
+        Cast->setSubExpr(nullptr);
+        TheCall->setArg(NumArgs-1, CastArg);
+      }
----------------
I think this should be combined with the code above. Something like:
```
bool IgnoreCast = false;
if (CastArg-> is Float) {
  assert(stuff);
  IgnoreCast = true;
} else if (CastArg-> is Half) {
  assert(stuff);
  IgnoreCast = true;
}

if (IgnoreCast) {
  Cast->setSubExpr(nullptr);
  TheCall->setArg(NumArgs - 1, CastArg);
}
```
