[PATCH] D57836: [Intrinsic] Unsigned Fixed Point Saturation Multiplication Intrinsic

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope updated this revision to Diff 218208.
bjope added a comment.

Commandeered (from leonardchan).
Rebased.
Now being based on monorepo.
Fixed bugs in LangRef.
Fixed bugs in ExpandIntRes_MULFIX (basically reimplemented saturation for UMULFIXSAT after breaking it out into a separate if-clause (no longer implementing shift by scale, signed saturation and unsigned saturation in the same piece of code).
