[Mesa-dev] [PATCH 00/10] 8-bit arithemtic

[Alyssa Rosenzweig]

This change set implements support for disassembly 8-bit arithmetic in
Midgard, as exposed via the (u)char OpenCL types. This is far from
complete, but it does a decent job for some more basic 8-bit-using
shaders.

This is a prerequisite to a decent implementation of programmatic
blending, since the blend pipeline is required to pack the pixel format
itself. For RGBA8, this means some 8-bit arithmetic in the blend shader.

Alyssa Rosenzweig (10):
  panfrost/midgard: reg_mode_full -> reg_mode_32, etc
  panfrost/midgard/disasm: Catch mask errors
  panfrost/midgard/disasm: Extend print_reg to 8-bit
  panfrost/midgard/disasm: Fill in .int mod
  panfrost/midgard: Fix crash on unknown op
  panfrost/midgard: Rename ilzcnt8 -> iclz
  panfrost/midgard/disasm: Support 8-bit destination
  panfrost/midgard/disasm: Print 8-bit sources
  panfrost/midgard/disasm: Stub out 64-bit
  panfrost/midgard/disasm: Handle dest_override generalized
