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.

Changes in v2:
- No longer adds tessellation enums
|

core.h is the public header of core mesa. GLX, WGL, and GLSL are
supposed to include this header file. It should be noted that headers
included by core.h must not perform feature tests (#if FEATURE_xxx).
Otherwise, we cannot, for example, mix a FEATURE_ES2 libmesagallium.a
with a FEATURE_GL libglsl.a.

mtypes.h does not use any symbols from compiler.h.
Also add the required headers for files that depended on symbols from
compiler.h but were indirectly including compiler.h through mtypes.h.
|
|
Now drivers, etc. can know which register files are accessed with
indirect addressing. Before we just checked gl_program::NumAddressRegs
but didn't know if that was the constant buffer, temp regs, or what.
The only user of this new field so far will be the gallium state tracker.
|
|
This pulls in multiple i965 driver fixes which will help ensure better
testing coverage during development, and also gets past the conflicts
of the src/mesa/shader -> src/mesa/program move.

This is an invasive set of changes. Each user shader tracks a set of other
shaders that contain built-in functions. During compilation, function
prototypes are imported from these shaders. During linking, the
shaders are linked with these built-in-function shaders just like with
any other shader.

These 3 fields are per shader-program. Copy them into the geometry
program at link time for convenient access later.
Also, add some missing glGetProgramiv() queries.
|
|
|
|
|
|
The can be at most one shader per stage. There are currently only two
stages. There is zero reason to dynamically size this array.
|
|
This avoids more allocation and shuffling of data around.
|
|
This saves recompiling at link time. gl_shader->ir is made a pointer
so that we don't have to bring exec_list into mtypes.h.
|
|
laying down the foundation for everything and implementing most of the
stuff.
linking, gl_VerticesIn and multidimensional inputs are left.
|
|
Includes GL_ARB_transform_feedback2 which encapsulates transform feedback
state in objects.
|
|
Some compilers complain about this.
