Fix suggested by Ian Romanick.
R300 driver now works without segfault.

Make sure that all the values used in the clean-up code are initialized at
some point. It is still unclear to me as to why GCC does not complain. I
suspect the problem may be due to the depth of if-statement nesting.

The weak version of _glapi_DispatchTSD was removed from dri_util.c. As
stated in the bug report, this was only needed to support versions of libGL
that did not have this symbol. Versions of libGL without this symbol are no
longer supported at all, so it is totally irrelevant.

direct-rendering is possible on a given screen. It is not possible to
determine this by just looking at driDisplay.private in the display
structure. However, it is possible to determine this by looking at
driScreen.private in the screen structure. This field is only non-NULL if a
DRI driver has been successfully loaded and bootstrapped. Once we get to
that point, we know that direct-rendering is at least theoretically
possible.
This fixes bugzilla #2875.

CALL_by_offset, SET_by_offset, and GET_by_offset all had various problems.
The core issue is that parts of the device-independent code in Mesa assumes
that all functions have slots in the dispatch table. This is especially
true in the display list code. It will merrilly try to set dispatch
pointers for glVertexAttrib1fARB even if GL_ARB_vertex_program is not
supported. When the GET/SET/CALL macros are invoked, they would read a 0
from the remap table. The problem is that 0 is the dispatch offset for
glNewList!
One change is that the remap table is now initialized to be full of -1
values. In addtion, all of the *_by_offset marcos misbehave in an obvious
way if the specified offset is -1. SET_by_offset will do nothing,
GET_by_offset will return NULL, and CALL_by_offset, since it uses
GET_by_offset, will segfault.
I also had to add GL_EXT_blend_func_separate to the list of default
extensions in all_mesa_extensions (src/mesa/drivers/dri/common/utils.c).
Even though many drivers do not export this extension, glBlendFunc is
internally implemented by calling glBlendFuncSeparate. Without this
addition, glBlendFunc stopped working on drivers (such as mga) that do not
export GL_EXT_blend_func_separate.
There are still a few assertions / crashes in GL_ARB_vertex_program tests,
but I don't think that these are related to any of my changes.

DRI drivers using the "old" interface relied on certain fields being at
certain offsets. Removing the structures would break that. Now that the
old interface is no longer supported, the dead data can finally die.

linux-dri, but it disables support for direct-rendering in it. This config
mainly exists so that I can verify that changes to libGL haven't broken
builds on non-DRI platforms.

for X on a miniglx fix. It can be removed later.
|
|
Code is already in DRM driver to do this.
|
|
I have tested these on miniglx and they seem to be working.
I'm sure Dave will give them a better test.

destroy __GLcontextModes structures. This eliminates the need for DRI
drivers to ever link with glcontextmodes.c.
|
|
Therefore, drivers should not require it to run.

_glapi_add_entrypoint has been replaced by a new routine called
_glapi_add_dispatch. This new routine dynamically assignes dispatch offsets
to functions added. This allows IHVs to add support for extension functions
that do not have assigned dispatch offsets.
It also means that a driver has no idea what offset will be assigned to a
function. The vast majority of the changes in this commit account for that.
An additional table, driDispatchRemapTable, is added. Functions not in the
Linux OpenGL ABI (i.e., anything not in GL 1.2 + ARB_multitexture) has a
fixed offset in this new table. The entry in this table specifies the
offset in of the function in the real dispatch table.
The internal interface was also bumped from version 20050725 to 20050727.
This has been tested with various programs in progs/demos on:
radeon (Radeon Mobility M6)
r128 (Rage 128 Pro)
mga (G400)

- The test for whether or not we're building for 64-bit is '#ifdef __arch64__'.
This appears to be correct on both Linux and Solaris.
- The test for Solaris is now '#if defined(SVR4) || defined(__SVR4) ||
defined(__svr4__)'. GCC 3.4.0 has all three defined on Solaris 9.
- Enables assembly language clip routines.
- Fixes to make GLSL code build on Solaris.
- Update gl_SPARC_asm.py.

A couple other remnants of the old interfaces hit the dust too. Thanks

that are currently obtained via glXGetProcAddress and all of the XF86DRI
functions are replaced with a funciton table. This table will be passed to
__driCreateNewScreen.
One of the functions in the table is getProcAddress. This allows some
loaders to expose functionality not in all loaders. This will be immediatly
used for glxEnableExtension (formerly known to drivers as
__glXScrEnableExtension). libGL (and in the future libglx) expose this
function so that drivers can enable GLX extensions. libEGL should exposed
eglEnableExtension to enable EGL extensions. The same function cannot be
used for both because the extensions have different names and (possibly)
different semantics. Drivers can optionally use one, both, or neither.
The key parts are in the __DRIinterfaceMethodsRec structure in
dri_interface.h. A pointer to one of these structures is passed into
__driCreateNewScreen. Because of this, the version of the API is bumped to
20050725. Since the previous version(s) were never in a release, their
existance is erased.
I was actually a little surprised by how much code this cuts from the
drivers. A lot of glXGetProcAddress calls disappear, and a lot of
version checks go with them. Nice.
The one thing I'm not sure of is removing __glXInitialize. For some
reason that function was in the glXGetProcAddress table, but *nothing*
in the Mesa tree used it. Did something with DRI conf. use this
function? It seems odd...

Set ctx->Const.MaxTextureLevels = GAMMA_TEX_MAXLEVELS = 12
Remove bogus WRITE(level 12).
Max gamma texture size is 2kx2k (note: 2k = 1 << (MaxLevels - 1))

linking, if relevant.
Updated Makefiles to use -linker option instead of setting CC, CXX env vars.
