[Mesa-dev] Status of radeonsi NIR

[Benedikt Schemmer]

Hi Timothy,

actually I am a subscriber to the list, dont know why this happens from
time to time

Benchmarkwise: NIR is now on par with TGSI, I put up some new HUD
screenshots and benchmarks

You might actually be too conservative: TGSI shows 2 spills, NIR 0


For now only two things stand out: some crashes during shader generation
in Deus Ex, Dying Light and Dead Island (Original) (see nir test) and
TressFX not working correctly in Tomb Raider.
