Nicolai,
Have you thought about switching to NIR for radeonsi completely to get
16-bit support? We need NIR support anyway for spirv, right? Would be
it be easier than adding 16-bit support into TGSI, glsl2tgsi, and
tgsi2llvm?
Well. What's missing from the NIR path is:
(1) GS and tess (the ABI parts only)
(2) re-adding some minor extensions (shader_group_vote?)
(3) fixing all the bugs -- it's been a while since I've done a piglit
comparison
There's a bunch of unknowns, so it's hard to say, but once we're there
16-bit should be much easier, so may be worth it.
Hi Nicolai,
Do you have a branch somewhere with your latest work on this? Or is it
all in Mesa currently?
I tried to run master on shader-db to see if the NIR path gave us any
big changes either way. However I had to stop it as it hit 11GB of mem
and rising. Not sure yet if this was a memleak, or we got stuck in a
loop somewhere.
Cheers,
Nicolai
