Author: Samuel Pitoiset <[email protected]> Date: Thu May 24 22:55:54 2018 +0200 radv: run the EarlyCSEMemSSA LLVM pass It's recommended by the instruction combining pass, and RadeonSI also runs it. This pass used to segfault with one shader of F12017 in the past, but it no longer crashes. Maybe the LLVM IR generated by RADV has changed.
