Ok, I came up with:
https://hastebin.com/bulilojupo.cpp
if you want to double check my methodology.
It spotted a couple small mistakes, which I've fixed up locally. Will
resend once I finish autotools build support.. hmm, and I guess there
is scons too.. *sigh*
Fwiw, one if the bugs was from this confusion about num_indices:
/* src[] = { vertex, offset }. const_index[] = { base, component } */
LOAD(per_vertex_output, 2, 1, BASE, COMPONENT, xx,
NIR_INTRINSIC_CAN_ELIMINATE)
;-)
I *guess* I should assume the original code was correct, and change this to:
# src[] = { vertex, offset }. const_index[] = { base }
load("per_vertex_output", 2, [BASE], [CAN_ELIMINATE])
?
