[Mesa-dev] [PATCH 00/10] GL_OES_get_program_binary extension

[Tapani Pälli]

Hi;

Here's the binary shader patch-set, I've fixed issues Paul found 
in the review earlier. There are lots of little changes but mainly: 

- more validation done when reading, also a special validation structure 
is introduced to bail out early if things do not seem to match, reading 
checks that we are not attempting to read over the blob boundary
- smaller blob size, now uniform storage is not serialized but gets 
generated as zero and constant initializer values are set if needed
- each user glsl type is serialized only once (requested by Paul)
- no more LinkShader call, now there is enough post-link information 
(this tested for Intel driver, others might require more)

branch with changes:
http://cgit.freedesktop.org/~tpalli/mesa/log/?h=oes_get_program_binary

branch that automatically caches linked programs and loads them on link:
http://cgit.freedesktop.org/~tpalli/mesa/log/?h=automatic_cache
(experiment to validate the extension functionality with any app)

I've been testing this set with a particular gles2 engine that supports 
binary caching. Also I've run automatic_cache on glbenchmark and some other 
random applications. I'm planning to make changes for Piglit shaderrunner to 
support cache so that Piglit could be used for the validation.

I know that Paul is very busy ATM so I would appreciate if someone else has 
time to go through some of this, thanks!
