[PATCH] D77152: [SelectionDAG] Better legalization for FSHL and FSHR

[Alex Bradbury via Phabricator via llvm-commits]

asb added a comment.

No objections accepting from the RISC-V side. I don't have a set of execution tests for the fshl/fshr changes to validate them, but I didn't see anything obviously wrong. The changes primarily affect the (still experimental) bitmanip extension also, so the bar for review is somewhat lower. The change does seem to improve srliw lowering in a few places in the GCC torture suite as well (in a way that is both correct and beneficial).
