These two assertions are invalid for a couple reasons. Primarily,
when this code is compiled into the X-server, the symbols
"glSecondaryColor3fEXT" and "glPointParameterivNV" do not exist.
I always build with -DGLX_USE_TLS, so I never hit these paths. glapi.h is
required in some places because _glapi_Dispatch is declared there, but
_glapi_tls_Dispatch is declared in glthread.h.
glDeleteTextures and glDeleteTexturesEXT were erroneously listed as
aliases of each other. For anything /except/ GLX protocol they are
aliases. This set of changes allows functions that are functionally
identical but have different GLX protocol to be listed as aliases.
When building with GLX_INDIRECT_RENDERING set, different static
functions are used. These functions determine whether the current
context is direct rendering or not. If the context is direct
rendering, the aliased function (e.g., glDeleteTextures in the case of
glDeleteTexturesEXT) is called. If the context is not direct
rendering, the correct GLX protocol is sent.

x86. This means that the position of each dispatch function can be
calculated as (dispatch_offset * size_of_function) + glNewList. This
allows us to not store the function pointers in glprocs_table_t.
This same optimization has been done for quite some time on x86. We
could probably also do this for some cases of the SPARC dispatch as
well.
boolean attribute, which defaults to true, determines whether or not a
static dispatch function is available in libGL for applications to link
against.
Ideally, any new functions that are not part of the ABI should not have
directly accessable dispatch functions. This forces applications to use
glXGetProcAddress to access these functions. By doing this we can
gracefully remove functions from libGL without breaking the linkage of
applications.
Note that the static dispatch functions are still generated. However, they
are given names like gl_dispatch_stub_820 and are marked with the "hidden"
linker attribute.
All extension functions added since the previous Mesa release (6.5) have
been marked as 'static_dispatch="false"'.
the driver. The loader now takes care of this for the driver.
Remove _glapi_DispatchTSD and give _glapi_Dispatch its semantic (i.e.,
having a NULL value means that the application is multithreaded and
_glapi_get_dispatch must be called).
Gut all of the dispatch override code. This removes _glapi_RealDispatch,
_glapi_tls_RealDispatch, _glapi_begin_dispatch_override,
_glapi_end_dispatch_override, and _glapi_get_override_dispatch.
Remove _glapi_get_proc_address, _glapi_get_proc_name, _glapi_get_version,
and _glapi_check_table from the loader / driver interface.

_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.
code in _glapi_set_dispatch to its 1.74 form. This fixes a "problem"
with buggy apps that make GL calls with no bound GL context (i.e.,
Enemy Territory during shut-down).
Replaced ctx->Color._DriverDrawBuffer with swrast->CurrentBuffer.
Replaced ctx->Pixel._DriverReadBuffer with ctx->Pixel._ReadSrcMask.
swrast->Driver.SetBuffer() takes FRONT/BACK_LEFT/RIGHT_BIT values now.
Added tokens and code for GL_AUX buffers, for completeness.
(provided we're on x86 or SPARC). Later, _glapi_add_entrypoint() will fix-up
the dispatch offset (which was -1). This will allow DRI libGL to avoid
probing for drivers.
