This is a poor substitute for proper global dead code elimination that could replace both our current paths, but it was very easy to write. It particularly helps with Valve's shaders that are translated out of DX assembly, which has been register allocated and thus have a bunch of unrelated uses of the same variable (some of which get copy-propagated from and then left for dead). shader-db results: total instructions in shared programs: 1735753 -> 1731698 (-0.23%) instructions in affected programs: 492620 -> 488565 (-0.82%) v2: Fix comment typo Reviewed-by: Matt Turner <mattst88@gmail.com> |
