[PATCH] D126540: PowerPC] Emit warning for incompatible vector types that are currently diagnosed with -fno-lax-vector-conversions

[Amy Kwan via Phabricator via cfe-commits]

amyk added a comment.

Some additional minor comments.



================
Comment at: clang/include/clang/Basic/DiagnosticSemaKinds.td:7572
+  "Current bitcast for incompatible vector types (%0 and %1) are deprecated. "
+  "The default behaviour will change to what implied by the "
+  "-fno-lax-vector-conversions option">,

+bool Sema::areAnyVectorTypesAltivec(QualType SrcTy, QualType DestTy) {
+  assert(DestTy->isVectorType() || SrcTy->isVectorType());
----------------
Can we add some brief documentation for this function, like what is done for other functions in this file?

+bool Sema::areAnyVectorTypesAltivec(QualType SrcTy, QualType DestTy) {

----------------
Can we add a message to this `assert()`?

+  if (SrcTy->isVectorType())
+  {
+    VectorType::VectorKind SrcVecKind = SrcTy->castAs<VectorType>()->getVectorKind();

nit: Can we put braces on the same line? (And same goes for 7727)

Unnecessary change?
