From 5e331e4ce85ad37dca45739846c2a801f06ab573 Mon Sep 17 00:00:00 2001 From: Bjorn Pettersson Date: Sat, 7 Sep 2019 12:16:14 +0000 Subject: [Intrinsic] Add the llvm.umul.fix.sat intrinsic Summary: Add an intrinsic that takes 2 unsigned integers with the scale of them provided as the third argument and performs fixed point multiplication on them. The result is saturated and clamped between the largest and smallest representable values of the first 2 operands. This is a part of implementing fixed point arithmetic in clang where some of the more complex operations will be implemented as intrinsics.
