[Mesa-dev] [PATCH v2 0/7] i965/gen7 instanced GS support for ARB_gpu_shader5

[Jordan Justen]

v2:
 * Convert gl_InvocationID to a system value

No piglit regressions on HSW.

MESA_EXTENSION_OVERRIDE=GL_ARB_gpu_shader5 allows piglit
arb_gpu_shader5/execution/invocation-id-basic.shader_test
to pass.

There are known issues with invalid layout qualifiers being
allowed by the compiler. (Most are pre-existing bugs)
Piglit master has tests highlighting these issues.

Patches are available at:
git://people.freedesktop.org/~jljusten/mesa gs-inv-id-v2

Jordan Justen (7):
  glsl: parse invocations layout qualifier for ARB_gpu_shader5
  glsl/linker: produce gl_shader_program Geom.Invocations
  mesa: initialize gl_geometry_program Invocations field
  main/shaderapi: GL_GEOMETRY_SHADER_INVOCATIONS GetProgramiv support
  glsl: add gl_InvocationID variable for ARB_gpu_shader5
  i965: support gl_InvocationID for gen7
  i965: support instanced GS on gen7
