This is now basically the same as the original VALUMaskWriteHazard, except it now considers both VALU and SALU writes. Now that it's a part of VALUMaskWriteHazard, differences from the original VALU lanemask workaround are: - it includes SALU reads after the write - it includes VALU writes and SALU/VALU reads after the write which are not lanemasks - it combines s_waitcnt_depctr instructions when it's a read after both a SALU write and a VALU write - non-exec VALU SGPR reads reset the SGPRs read by VALU as a lanemask - exec SGPRs are ignored resolve_all_gfx11() is also finished. fossil-db (navi31): Totals from 21538 (27.13% of 79377) affected shaders: Instrs: 27628855 -> 27552972 (-0.27%); split: -0.30%, +0.03% CodeSize: 145968448 -> 145667616 (-0.21%); split: -0.23%, +0.02% Latency: 209537805 -> 209509519 (-0.01%); split: -0.02%, +0.00% InvThroughput: 36304270 -> 36301624 (-0.01%); split: -0.01%, +0.00% Signed-off-by: Rhys Perry <pendingchaos02@gmail.com> Reviewed-by: Georg Lehmann <dadschoorse@gmail.com> Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/12623 Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/11480 Backport-to: 25.0 Backport-to: 25.1 Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/34529>
