[Mesa-dev] [PATCH 00/19] AMD support for NIR deref instructions.

[Bas Nieuwenhuizen]

This implements support in radv and radeonsi for NIR deref
instructions instead of deref chains.

It contains 4 parts:
- patch 1 is a fixup for the initial series by Jason
- Add support everywhere for instruction based derefs
- Stop lowering them to deref chains (may need to be synchronized
  with other drivers and core nir code to keep things bisectable)
- Remove support for deref chains.
