Shader variants are stored in the list, the key for lookup is based on the
states that require different hw shaders - currently it's rctx->two_side (all
gpus) and rctx->nr_cbufs (evergreen/cayman, when writes_all property is set).
v2:
- use simple list instead of keymap as suggested by Marek on irc
- call r600_adjust_gprs from r600_bind_vs_shader for r6xx/r7xx
(r600_shader_select isn't used for vertex shaders currently)
v3:
- fix call to r600_adjust_gprs - do it after updating current shader
Improves performance for some apps, e.g. FlightGear -

These all return zero. Add a debug_printf() to catch the default case so
we don't accidently mishandle something important in the future.

This is actually required for GL_ARB_framebuffer_object, but the state

Direct3D 9 allows mixed format color buffers with some restrictions.
Setting this allows Unigine Heaven 2.5 and 3.0 to run. Tested both on

It was only no-oping the clear() function, not actual triangle
rasterization. Move the no_rast field from lp_context down into
lp_rasterizer so it's accessible where it's needed.

$CLANG_RESOURCE_DIR is the directory that contains all resources
needed by clang to compile programs. When clover uses clang to
compile kernels it needs to specify a resource dir, so that clang
can find its internal headers (e.g. stddef.h).
clang defines $CLANG_RESOURCE_DIR as $CLANG_LIBDIR/clang/$CLANG_VERSION
This patch adds the --with-clang-libdir option in order to accommodate
clang intalls to non-standard locations, and it also adds a check
to the configure script to verify that $CLANG_RESOURCE_DIR/include
contains the necessary header files.
It's not optimal, but it's better than the register pressure scheduler
that was previously being used. The VLIW scheduler currently ignores
all the complicated instruction groups restrictions and just tries to
fill the instruction groups with as many instructions as possible.
Though, it does know enough not to put two trans only instructions in
the same group.
We are able to ignore the instruction group restrictions in the LLVM
backend, because the finalizer in r600_asm.c will fix any illegal
instruction groups the backend generates.
Enabling the VLIW scheduler improved the run time for a sha1 compute
shader by about 50%. I'm not sure what the impact will be for graphics
shaders. I tested Lightsmark with the VLIW scheduler enabled and the
framerate was about the same, but it might help apps that use really
big shaders.
Every place that uses ASM_FLAGS already uses DEFINES. Not including
it in DEFINES is just a way to screw up potential users, as I've done
several times while working on the build system.
1) We need to insert a barrier between consecutive transform feedback calls.
2) VBO cache needs to be flushed when TFB output is used as VBO draw input.
Fixes Piglit test EXT_transform_feedback/immediate-reuse.
Thanks to Christoph Bumiller for pointing out bugs in previous versions
of this patch.
The system array values concept doesn't really because it expects the
system values to be fixed per call, which is wrong for gl_VertexID and
iffy for gl_SampleID. So this patch does two things:
- kill the array, have emit_fetch_system_value directly pick the
values it needs (only gl_InstanceID for now, as the previous code)
- correctly handle the expected type in emit_fetch_system_value

- copying the flatshaded attributes when needed, including the

- correctly interpolating the noperspective attributes in screen-space

This is failing sometimes, probably because TargetData keeps a structure layout
cache, which can becomes bogus, ever since the InvalidateStructLayoutInfo API
was removed in LLVM r135245.
This change merely makes the problem easier to diagnose (an assertion
failure instead of a random crash).
This requires the latest streamout kernel patches.
Streamout is disabled by default on r7xx, so this patch is safe for regular
users.
