[Mesa-dev] [PATCH 0/3] Implement location aliasing checks for SSO programs

[Iago Toral Quiroga]

As discussed in reply to my series that fixes this for non-SSO paths [1],
this series  builds on top of that to also handle SSO programs.

I checked that this works by adding SSO ENABLED to these two piglit tests:
tests/spec/arb_enhanced_layouts/linker/block-member-locations/named-block-member-location-overlap.shader_test
tests/spec/arb_enhanced_layouts/linker/block-member-locations/named-block-member-mixed-order-overlap.shader_test

I guess we want to have versions of these with SSO ENABLED in piglit so
I'll send patches next week to do that.

  glsl/linker: create a helper function to validate explicit locations
  glsl/linker: generalize validate_explicit_variable_location for SSO
  glsl/linker: validate explicit locations for SSO programs
