[Mesa-dev] [PATCH v2 0/3] Lower UBO/SSBO access early

[Kristian Høgsberg Kristensen]

Here's v2 of the series I sent out yesterday. Nothing changed in what
we're trying to do, but I figured out the shader-db regression.

I used ir_type_variable instead of ir_type_dereference_variable when
trying to make opt_dead_code_local not stomp on my vector array deref
lvalue. As a result, the pass now failed to eliminate some cases of dead code.

This v2 series, now has no shader-db impact and no jenkins regressions.

Kristian Høgsberg Kristensen (3):
  glsl: Drop exec_list argument to lower_ubo_reference
  glsl: Lower UBO and SSBO access in glsl linker
  glsl: Use array deref for access to vector components
