Subject: freedreno/ir3: turn on [iu]mul_high
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ad259482610048e0e3cc8fc0cacd4581f1256b5d;p=mesa.git

freedreno/ir3: turn on [iu]mul_high

Which also requires uadd_carry lowering

Until recently this was lowered in glsl ir so it went unnoticed that we
weren't lowering it.

Fixes: 1d8994a63b5 glsl: [u/i]mulExtended optimization for GLSL
