[PATCH] D44559: [Sema] Wrong width of result of mul operation

[John McCall via Phabricator via llvm-commits]

I think we're correct not to warn here and that GCC/ICC are being noisy.  The existence of a temporary promotion to a wider type doesn't justify warning on arithmetic between two operands that are the same size as the ultimate result.  It is totally fair for users to think of this operation as being "closed" on the original type.
