[Mesa-dev] [PATCH 0/9] nir shared variable support

[Jordan Justen]

This patchset allows nir to support shared variable. It works well
with our SPIR-V support in the Intel Vulkan driver.

I've also tried to get GLSL to delay shared variable lowering to allow
it to be handled later in nir, but I got caught up in various places
within the GLSL compiler. Oh well... giving up for now since the other
path works fine, and the Intel Vulkan driver needs this.

Jordan Justen (9):
  nir/print: Add space after shader_storage var mode
  nir: Add compute shader shared variable storage class
  squash: Increase nir_variable_data::mode to 5 bits
  nir: Add atomic operations on variables
  nir: Add support for lowering load/stores of shared variables
  nir: Lower shared var atomics during nir_lower_io
  i965/nir: Lower nir compute shader shared variables
  nir/glsl_to_nir: Initialize num_shared
  i965: Use num_shared from nir_shader for shared variables size
