This implements the extension by choosing a different set of texture
fetch functions when the texture parameter changes.

Add a bit in struct gl_extensions for OES_standard_derivatives, and enable
the bit by default. Advertise the extension only if the bit is enabled.
Previously, OES_standard_derivatives was advertised in GLES2 contexts
if ARB_framebuffer_object was enabled.

|
Place GL, GLES1, and GLES2 extensions in a unified extension table. This
allows one to enable, disable, and query the status of GLES1 and GLES2
extensions by name.
When tested on Intel Ironlake, this patch did not alter the extension
string [as given by glGetString(GL_EXTENSIONS)] for any API.

Right now this is just tweaking the current code to look at the table.
Choosing actually supported formats will come later.
|

System values are shader inputs which don't necessarily change from
vertex to vertex or fragment to fragment. gl_InstanceID and
gl_FrontFacing are examples.

This allows 16K x 16K 2D textures, for example, but we don't want to
allow that for 3D textures. The new gl_constants::MaxTextureMBytes
field is used to prevent allocating too large of texture image.
This allows a 16K x 32 x 32 3D texture, for example, but prevents 16K^3.
Drivers can override this limit. The default is currently 1GB.
Apps should use the proxy texture mechanism to determine the actual
max texture size.

DD_POINT_SIZE was broken for quite some time, and the only driver (r200) relying
on this no longer needs it.
Both DD_POINT_SIZE and DD_LINE_WIDTH have no users left outside of debugging
output, hence instead of fixing DD_POINT_SIZE setting just drop both of them -
there was a plan to remove tricaps flags entirely at some point.
|
|
It was in the middle of the lighting-related structures before.
Also add some info about field sizes in this structure.

The assumption is that all stages are the same program or that
varyings are passed between stages using built-in varyings.
|
|
ActiveProgram is the GL_EXT_separate_shader_objects state variable
used for glUniform calls. glUseProgram also sets this.

Previously _LinkedShaders was a compact array of the linked shaders
for each shader stage. Now it is arranged such that each slot,
indexed by the MESA_SHADER_* defines, refers to a specific shader
stage. As a result, some slots will be NULL. This makes things a
little more complex in the linker, but it simplifies things in other
places.
As a side effect _NumLinkedShaders is removed.
NOTE: This may be a candidate for the 7.9 branch. If there are other
patches that get backported to 7.9 that use _LinkedShader, this patch
should be cherry picked also.

Just always check for FLUSH_UPDATE_CURRENT and call Driver.BeginVertices
when necessary. By using the unlikely() macros, this ends up as
a 10% performance improvement (for isosurf, anyway) over the old,
complicated function pointer swapping.

__GLcontextModes is always only used as an implementation internal struct
at this point and we shouldn't install glcore.h anymore. Anything that
needs __GLcontextModes should just include the struct in its headers files
directly.

This adds proper support for the GL_ARB_shader_stencil_export extension
to the GLSL compiler. Thanks to Ian for pointing out where I need to add things.

this is needed to add support for stencil shader export.

EXT_texture_compression_rgtc
Change the name in the extension tracking structure to ARB (from EXT).
|
|
This is only used in the i915 driver where it provides little benefit
for very few applications that use it with fixed function TNL.
|
|
This extension was never enabled in any driver.
|
|
More optional code.
|
|
Another optional ARB_imaging subset extension.

|
Another optional ARB_imaging subset extension.
|
|
This has always been optional, and not useful.
|
|
Many of the EXT_ extensions in the subset have significant code
overhead with no users. It is not a required part of GL -- though
text describing the extension is part of the core spec since 1.2, it
is always conditional on the ARB_imaging extension.
|
|
Instead of using the invalid GL_ARB_shading_language_120 extension to
determine the GLSL version, use a new ctx->Const.GLSLVersion field.
Updated the intel and r600 drivers, but untested.
See fd.o bug 29910
NOTE: This is a candidate for the 7.9 branch (but let's wait and see if
there's any regressions).

This reverts commit b9abc6139a310677a37754ea7172d976dbf56979 and the
follow on fixes (7aae704 and 6fe1b47). It's changing the glapi/driver
ABI and causes a number of problems for debug/non-debug builds.
|
|
|
|
There's a useful feature buried in glapi to log all API calls to stderr.
Unfortunately it requires editing the code and then it's enabled
unconditionally for that build. This patch builds in API logging for
debug builds and makes it run-time switchable by setting MESA_DEBUG=dispatch.
|
|
This increases the chance that GLSL programs will actually work.
Note that continues and returns are not yet lowered, so linking
will just fail if not supported.

This allows us to specify different options, especially useful for chips
without unified shaders.
