[Mesa-dev] [PATCH 00/12] RFC: add support of ARB_separate_shader_object extensions V3

[Gregory Hainaut]

Please find an implementation of the ARB_separate_shader_objects extensions. I concentrate
mostly on the state part of the extensions aka the pipeline object. I think GLSL
already compiled program separately anyway.

I test my implementation on the test that I send on piglit mailing list. All tests 
are ok but I miss a test for new uniform function. Besides there are still some parts unimplemented:
1/ GLX Protocol: dropped
2/ Display list: would be done later if someone is interested otherwise dropped

Stuff that bug me:
1/ I implement the feature as a pure mesa state. I don't know if they're any rule to create driver functions. Maybe it 
   would be better to add CreatePipelineObject/DeletePipelineObject/BindPipeline/UseProgramStages. Opinion is welcome

A github branch can be found here (based on v2 but v3 add only comment):
* https://github.com/gregory38/mesa-sso/tree/sso2

V2: 
* fix ralloc memory leak
* follow mesa formating rule
* rename Pipeline.PipelineObj to Pipeline.Current
* rename gl_shader_state to gl_pipeline_object
* rebase on current mesa

V3:
* resend properly the patches on the mesa mailing list
* Add minor comment


Note: Rebase done on ac1118d53c0b22db8dcd6fcdcd2d1a245037dbc1

Gregory Hainaut (12):
  sso: Create extensions entry points

  sso: implement ActiveShaderProgram & GetProgramPipelineiv
  sso: replace Shader binding point with _Shader
  sso: rename Shader to the pointer _Shader
  sso: update meta state
  sso: Implement _mesa_UseProgramStages
  sso: implement BindProgramPipeline
  sso: update glGet: GL_PROGRAM_PIPELINE_BINDING
  sso: implement ValidateProgramPipeline and GetProgramPipelineInfoLog
