clover: Add --with-clang-libdir option and verify CLANG_RESOURCE_DIR

$CLANG_RESOURCE_DIR is the directory that contains all resources

compile kernels it needs to specify a resource dir, so that clang

clang intalls to non-standard locations, and it also adds a check
to the configure script to verify that $CLANG_RESOURCE_DIR/include

11 years agoi965: Compute dFdy() correctly for FBOs.
Paul Berry [Wed, 20 Jun 2012 20:40:45 +0000 (13:40 -0700)]
i965: Compute dFdy() correctly for FBOs.

On i965, dFdx() and dFdy() are computed by taking advantage of the
fact that each consecutive set of 4 pixels dispatched to the fragment
shader always constitutes a contiguous 2x2 block of pixels in a fixed
arrangement known as a "sub-span".  So we calculate dFdx() by taking
the difference between the values computed for the left and right
halves of the sub-span, and we calculate dFdy() by taking the
difference between the values computed for the top and bottom halves
of the sub-span.

However, there's a subtlety when FBOs are in use: since FBOs use a
coordinate system where the origin is at the upper left, and window
system framebuffers use a coordinate system where the origin is at the
lower left, the computation of dFdy() needs to be negated for FBOs.

This patch modifies the fragment shader back-ends to negate the value
of dFdy() when an FBO is in use.  It also modifies the code that
populates the program key (brw_wm_populate_key() and
brw_fs_precompile()) so that they always record in the program key
whether we are rendering to an FBO or to a window system framebuffer;
this ensures that the fragment shader will get recompiled when
switching between FBO and non-FBO use.

This will result in unnecessary recompiles of fragment shaders that
don't use dFdy().  To fix that, we will need to adapt the GLSL and
NV_fragment_program front-ends to record whether or not a given shader
uses dFdy().  I plan to implement this in a future patch series; I've
left FIXME comments in the code as a reminder.

Fixes Piglit test "fbo-deriv".

NOTE: This is a candidate for stable release branches.

radeon/llvm: Use the VLIW Scheduler for R600->NI

It's not optimal, but it's better than the register pressure scheduler

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

Elsewhere in the spec, where multisample rasterization is described
(sections 3.4.3, 3.5.4, and 3.6.6), the following text is consistently
used:

    "If MULTISAMPLE is enabled, and the value of SAMPLE_BUFFERS is
    one, then..."

So, in other words, disabling GL_MULTISAMPLE should prevent
multisample rasterization from occurring, even if the draw framebuffer
is multisampled.  This patch implements that behaviour by setting the
WM and SF stage's "multisample rasterization mode" to
MSRAST_ON_PATTERN only when the draw framebuffer is multisampled *and*
GL_MULTISAMPLE is enabled.

i965/msaa: Disable unsupported formats.
