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.
Conflicts:
src/mesa/Makefile
src/mesa/main/shaderapi.c
src/mesa/main/shaderobj.h

On Cygwin locale_t in not available but 'llvm-config --cppflags' adds
the compiler flag -D_GNU_SOURCE to the build.

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.

When defining mipmap level 'L' and level L-1 exists and the new level's
internalFormat matches level L-1's internalFormat, then use the same hw
format. Otherwise, do the regular ctx->Driver.ChooseTextureFormat() call.
This avoids a problem where we end up choosing different hw formats for
different mipmap levels depending on how the levels are defined (glTexImage
vs. glCopyTexImage vs. glGenerateMipmap, etc).
The root problem is the ChooseTextureFormat() implementation in some
drivers uses the user's glTexImage format/type parameters in the choosing
heuristic. Later mipmap levels might be generated with different calls
(ex: glCopyTexImage()) so we don't always have format/type info and the
driver may choose a different format.

_mesa_meta_GenerateMipmap"

Found by Vinson with static analysis.
NOTE: This is a candidate for the 7.8 branch.

Add error path for unhandled dimensions in
compressed_texture_error_check.

Fixes piglit object_purgeable-api-pbo, object_purgeable-api-vbo
and object_purgeable-api-texture failures with swrast.

The other similar integer/float conversion macros are in macros.h.

Assert ctx->Driver.NewTransformFeedback if the feature is enabled; Use
the default callbacks otherwise. The rest of core mesa expects the
state to be initialized.

As defined by GL_EXT_texture_integer.

Check FEATURE_GL in _mesa_init_shader_dispatch and
_mesa_init_shader_uniform_dispatch. OpenGL ES can not and does not use
_mesa_init_<...>_dispatch. This is supposed to be temporary. Ideally,
a more flexible way for initializing dispatch tables should be
developed.

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.

Before, if there were no color buffers enabled (with glDrawBuffers(GL_NONE))
when the texenv program was generated, we'd emit writes to OUTPUT[1] but
the OutputsWritten mask was 0. This inconsistency caused an assertion to
fail later in the Mesa->TGSI translation.
Fixes fd.o bug 28169
NOTE: this is a candidate for the 7.8 branch (and depends on commit
b6b9b17d27c570cc99ae339e595cf2f63ca5e8d7).

|
All the state that effects the program should be in the key.
This didn't help with bug 28169 but is a good fix anyway.
NOTE: this is a low-priority candidate for the 7.8 branch. In practice,
this issue might never be hit.

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.

Patch from Brad Smith <brad@comstyle.com>
The attached patch allows the GL_OES_query_matrix function to use the
systems fpclassify() for OpenBSD and NetBSD.

...instead of waiting until glGetString(GL_EXTENSIONS) is called.
This fixes a problem where the MESA_EXTENSION_OVERRIDE env var is
ignored if the app never calls glGetString(GL_EXTENSIONS).
NOTE: this is a candidate patch for the 7.8 branch.

1. Move all GL entrypoint functions and files into src/mesa/main/
This includes the ARB vp/vp, NV vp/fp, ATI fragshader and GLSL bits
that were in src/mesa/shader/
2. Move src/mesa/shader/slang/ to src/mesa/slang/ to reduce the tree depth
3. Rename src/mesa/shader/ to src/mesa/program/ since all the
remaining files are concerned with GPU programs.
4. Misc code refactoring. In particular, I got rid of most of the
GLSL-related ctx->Driver hook functions. None of the drivers used
them.

This is a follow-on to commit 80dfec3e53fd5b5c8c31fb16376c9910258c91b0.
The valid attachments for glGetFramebufferAttachmentParameteriv() depends
on whether we're querying the default FBO or a user-created FBO.

If the default framebuffer is bound to <target>, then
<attachment> must be one of FRONT_LEFT, FRONT_RIGHT, BACK_LEFT,
BACK_RIGHT, AUXi, DEPTH_BUFFER, or STENCIL_BUFFER, identifying a
color buffer, the depth buffer, or the stencil buffer, and
<pname> may be FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE or
FRAMEBUFFER_ATTACHMENT_OBJECT_NAME.
as well as these <pname> values
FRAMEBUFFER_ATTACHMENT_RED_SIZE,
FRAMEBUFFER_ATTACHMENT_GREEN_SIZE,
FRAMEBUFFER_ATTACHMENT_BLUE_SIZE,
FRAMEBUFFER_ATTACHMENT_ALPHA_SIZE,
FRAMEBUFFER_ATTACHMENT_DEPTH_SIZE,
FRAMEBUFFER_ATTACHMENT_STENCIL_SIZE,
FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE, or
FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING.

Reduce the source tree depth a bit.

Remove the unneeded ctx->Driver hooks for shader-related functions.
Move state and API-related things into main/.
|
|
Drivers still reject them today, but cairo would like to use these.
|
|
The specifications are identical.
