Ok, so any torcs version should show a performance difference to check against.

Hi,
I have posted a very similar patch already with the array object change
series. But I have omitted applying this one because of a general issue that
Brian pointed me to in a patch prior to this one in the series.
But it turns out that this one should be still safe.
Please review
Thanks
Ma

A binding point is an uint that is referred by BindBuffer* and
UniformBlockBinding API function. A UBO in shader will fetch
data in the buffer that holds the same binding point.
Note that this patch should be reworked : it currently uses a
static array to hold binding points, and does not take car

GL_ARB_uniform_buffer_object API uses index as a way to query information about
classic uniform and variables in UBOs. For classic uniform, index does not have
to
match uniform location, but it is not forbidden and is simpler to implement.
Linker generates an array that stores in index order varia
UBO data can be packed using 3 different strategies : packed, shader and std140.
The spec defines in a non ambigous way the std140 strategy, this patch
implements
it.

GL_ARB_uniform_buffer_object spec defines standard layout rules to define how
data
are packed in a uniform buffer object, using offset and stride. A single
ir_variable::location is not enough to hold every possible case and thus we
defined a

This patch makes the linker checks UBO from several shader compatibility, and
merges
them if necessary, at intrastage step.

This patch brings 2 new structures:
- gl_shader_ubo_variable which holds name and type of a variable inside an ubo
- gl_uniform_buffer_object which holds UBO wide and variable informations in
the form
of a gl_shader_ubo_variable array.
This patch also updates parser front-end to fill these structu

A variable in a UBO is basically an uniform, and optimisation pass should sees
them as
such. ir_variable::mode for variable in an uniform is thus set to
ir_var_uniform.
However it is good to be able to quickly discriminate classic uniform vs
variable in an
UBO so another flag is added to ir_vari

Hi and merry chrismas everyone.
I have updated my UBO patch set to follow some recommandations from ML.
I splitted some patches (and for some of them, added a longer description).
The last three ones needs a bit more polishing though, and there might be
some leftover debug code or old comments tha

I did not fix Torcs. I think optimizing apps is useless if the same
optimization can be done in Mesa too.
