[Mesa-dev] [PATCH 00/23] ARB_program_interface_query

[Tapani Pälli]

Hello;

Here's the implementation of ARB_program_interface_query extension.
Patches add a resource list as part of gl_shader_program which contains 
all different resources. List is then used to implement extension 
functions as well as following existing queries:

GetActiveAttrib
GetAttribLocation
GetUniformLocation
GetActiveUniformName
GetUniformIndices
GetActiveUniform
GetActiveUniformsiv
GetUniformBlockIndex
GetActiveUniformBlockName
GetActiveUniformBlockiv
GetActiveAtomicCounterBufferiv
GetTransformFeedbackVarying
GetFragDataLocation
GetFragDataIndex

No Piglit regressions with these changes. There are only 2 new tests 
ATM for the extension but most (if not all) functionality is tested by 
tests for the functions above. Martin Peres and I will also implement 
further tests for the actual extension functions.

Extension specification:

Git branch with all the patches:
