[PATCH] D99469: GlobalISel: Restrict narrow scalar for fptoui/fptosi results

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/LegalizerHelper.cpp:4721
+  if (SrcTy.getScalarType() == LLT::scalar(16) &&
+      DstTy.getScalarSizeInBits() >= (IsSigned ? 17 : 16)) {
+    Observer.changingInstr(MI);
----------------
Shouldn't this check the NarrowTy, rather than the old DstTy?
