This caused Chromium builds to fail with "Illegal Trunc" assertion. See https://crbug.com/890723 for repro. > This transform is requested for the backend in: > https://bugs.llvm.org/show_bug.cgi?id=39016 > ...but I figured it was worth doing in IR too, and it's probably > easier to implement here, so that's this patch. > > In the simplest case, we are just truncating a scalar value. If the > extract index doesn't correspond to the LSBs of the scalar, then we > have to shift-right before the truncate. Endian-ness makes this tricky, > but hopefully the ASCII-art helps visualize the transform. > > Differential Revision: https://reviews.llvm.org/D52439 llvm-svn: 343458 |
