Re: [Mesa-dev] [PATCH] st/mesa: kill instruction if writemask=0 in eliminate_dead_code_advanced()
I don't think there's any reason we can't eliminate a dead instruction
when the writemask is zero. I do wonder, though, why this patch
actually makes a difference. There's an if (!inst-dead_mask ||
!inst-dst.writemask) three lines before the code visible in the patch
that makes it not kill the instruction if the writemask is zero. I
don't remember why that's there, but if it weren't there, and the
writemask is zero, the dead_mask should also be zero, so it should be
handled by the else if block.
In short, I think that entire if/else if/else statement could use a look.

What does it do if there's no destination register? In any case, I
don't think glsl_to_tgsi emits any ARLs of that form, so it shouldn't be
a problem.

Re: [Mesa-dev] [PATCH] st/mesa: kill instruction if writemask=0 in eliminate_dead_code_advanced()
Correct.
The thing was: even though we have an addressing register in TGSI
(e.g. tgsi_full_dst|src_register::Indirect), everybody except nv50 and
partially svga doesn't use it now. They expect the indirect register
file is always TGSI_FILE_ADDRESS and the index is 0, making the
destination of ARL irrelevant. This is probably a bug in those drivers
and that's what made me think that ARL doesn't need a destination
register. Sorry for the noise.
