This uses prog_to_nir to translate ARB assembly programs to NIR.
Co-authored by Tim Arceri, Dave Airlie, and Ken Graunke:
- [Tim Arceri]: original patch
- [Dave Airlie]: fix crashes with parameter names
- [Ken Graunke]:
- Rebase on SCALAR_ISA cap, lower wpos_ytransform too.
- Rebase on streamout fixes.
- Lower system values for fragcoord support.
- Don't try to use prog_to_nir for ATI_fragment_shader programs.
- Create TGSI for fixed-function or ARB vertex shaders even if the
driver prefers NIR, so we can create draw module shaders for
feedback/select emulation, which rely on TGSI.
Tested on:
- iris (Intel Skylake/Kabylake): Piglit & GL CTS - Ken Graunke
- radeonsi (AMD Vega 64): Piglit - Ken Graunke
- vc4/v3d - Piglit - Eric Anholt
- freedreno - dEQP - Kristian Høgsberg
Fixes lit_degenerate_case on vc4 and v3d, and vp-address-01,
vp-arl-constant-array-huge-offset-neg, and vp-arl-neg-array on v3d.
No Piglit regressions on radeonsi; no dEQP regressions on freedreno.
