[Mesa-dev] [PATCH 0/1] nir: new pass that removes continue blocks (+10% FPS with Doom on RADV)

[Samuel Pitoiset]

Hi,

I wrote that NIR pass few weeks ago when I was trying to improve performance
with Shadow Of The Tomb Raider, which has a bunch of complex loops.

While this pass doesn't really improve SotTR, it gives a huge boost
with DOOM (and probably DOOM VFR), +10% FPS on my Vega 56.

I have no ideas why LLVM isn't able to improve that itself, but I think
it might good to have this optimization directly in NIR.

Please review,
Thanks!
