there's no point in keeping deprecated PIPE_CAPS around since there's no
stable interface (yet).
Reuse the enum for PIPE_CAP_DUAL_SOURCE_BLEND. Drivers advertizing this
will accept the pipe blendfactors with SRC1 in them and be able to do dual
source blending (src color from pixel shader output 0, and blendfactor with
SRC1 will come from output 1, only one render target may be bound when using
any of these blend factors).
GL 3.0 (EXT_draw_buffers2) and other APIs allow independent blend enables and
write masks per render target, ARB_draw_buffers_blend (and other APIs) also
allow independent blend functions. Things like dithering, logic ops however
are not extended to be per rendertarget, that might be conceptually possible
however it doesn't look like any API wants to expose this.
Sun cc 5.9 and later (__SUNPRO_C >= 0x590) support __attribute__ calls
for aligned, always_inline, noinline, pure, const, and malloc.
This commit includes updates to files that were regenerated by gl_XML.py
after adding the __SUNPRO_C checks to it

Everybody is using the C99's integer types. Everybody except Microsoft,
which in turns means everybody is including their own definitions of C99
integer types for MSVC, causing duplicate definitions when linking two
projects. This is the case of building Gallium and LLVM with MSVC.
Shipping alternative stdint.h and stdbool.h headers for MSVC allows us
to share a single definition. It also removes clutter from the Gallium
headers.
This patch removes PIPE_TEX_FILTER_ANISO.
Anisotropic filtering is enabled if and only if max_anisotropy > 1.0.
Values between 0.0 and 1.0, inclusive, of max_anisotropy are to be
considered equivalent, and meaning to turn off anisotropic filtering.
This approach has the small drawback of eliminating the possibility of
enabling anisotropic filter on either minification or magnification
separately, which Radeon hardware seems to support, is currently
support by Gallium but not exposed to OpenGL. If this is actually
useful it could be handled by splitting max_anisotropy in two values
and adding an appropriate OpenGL extension.
NOTE: some fiddling & reformatting by keithw to get this patch to
apply. Hopefully nothing broken in the process.
Provide reference implementation of them in tgsi_exec.
Note that BREAK opcode is overloaded and can be used to break out
of either a loop or a switch-case statement.
For conditional rendering predicated on results of an occlusion query.
If this driver function is NULL, conditional rendering is not supported by
the driver.
it's a leftover from an early version of geometry shading support.
geometry shaders now encode the primitive size in the PROPERTY token
and don't need special input with their size.
The idea here is to eliminate the set_edgeflags() call in pipe_context
by treating edgeflags as a regular vertex element.
Edgeflags provoke special treatment in hardware, which means we need to
label them in some way, in this case we'll be passing them through the
vertex shader and labelling the vertex shader output with a new TGSI
semantic (TGSI_SEMANTIC_EDGEFLAG).
Historically, parts of mesa code are not strict-aliasing safe, hence
-fno-strict-aliasing is needed to compile (this got forgotten for scons
builds for gallium, which indeed not only caused compiler warnings but also
unexplicable crashes in non-debug builds). However, we should try to eliminate
code not complying with strict-aliasing code at least for gallium.
Hence change pipe_reference functions to make them strict-aliasing compliant.
This adds a bit more complexity (especially for derived classes) but is the
right thing to do, and it does in fact fix a segfault.
