[Mesa-dev] [PATCH v2 00/24] ARB_program_interface_query

[Tapani Pälli]

Hello;

Here's the v2 implementation of ARB_program_interface_query extension.
I have addressed errors found by Ilia Mirkin in his review and there 
are several small fixes here and there for bugs revealed with Martin's 
Piglit tests.

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 Piglit tests for the
extension in the Piglit mailing list, all of these pass:

Extension specification:
https://www.opengl.org/registry/specs/ARB/program_interface_query.txt

Git branch with all the patches:

Thanks;
