We were trying to emit a single ir_expression to compare the whole
thing. The backends (ir_to_mesa.cpp and brw_fs.cpp so far) expected
ir_binop_any_nequal or ir_binop_all_equal to apply to at most a vector
(with matrices broken down by the lowering pass). Break them down to
a bunch of ORed or ANDed any_nequals/all_equals.
Fixes:
glsl-array-compare
glsl-array-compare-02
glsl-fs-struct-equal
glsl-fs-struct-notequal
Bug #31909

This doesn't cover all expressions or all operand types, but it will
complain if you overreach and it allows for much greater slack on the
programmer's part.

Need this to trigger the scene to update its shadow of the constant
state.

we store into the index specified by the register index, not an
indirect register.

Fixes glsl-fs-fragdata-1, and hopefully Eve Online where I noticed
this bug in the generated shader. Bug #31952.

This code was for the old GLcore build of the software rasteriser. The
X server switched to a DRI driver for software indirect GLX long ago.

The spec says the border color should be consistent with the internal
format.

Tested with piglit + ut2004 still seems to render okay (and it
definitely does this)

There are also some u_simple_shaders changes.
On r300, the TGSI_SEMANTIC_COLOR varying is a fixed-point number clamped
to the range [0,1] and limited to 12 bits of precision. Therefore we can't
use it for passing through a clear color in order to clear high precision
texture formats.
This also makes u_blitter use only one vertex shader instead of two.

Since the viewport is not updated on RandR12 mode switches anymore,
clipping to viewport may incorrectly clip away the video.

This may help paint the colorkey before overlay updates in some
situations where the app paints the color key (mainly xine).

The compiler seriously needs a cleanup as far as the arrangement of functions
is concerned. It's hard to know whether some function was implemented or not
because there are so many places to search in and it can be anywhere and
named anyhow.

It looks like the function was originally written for ARB_fragment_program.

But the driver must be smart here and follow PIPE_TRANSFER_DISCARD,
as it should.

If nvfx_framebuffer prepare and validate were called successively with
fb->zsbuf not NULL and then NULL, nvfx->hw_zeta would contain garbage and
this would cause failures in nvfx_framebuffer_relocate/OUT_RELOC(hw_zeta).
This was triggered by piglit/texwrap 2D GL_DEPTH_COMPONENT24 and caused
first a 'write to user buffer!!' error in libdrm and then worse things.

Currently, the standalone compiler tries to do function inlining before
linking shaders (including linking against the built-in functions).
This resulted in the built-in function _prototypes_ being inlined rather
than the actual function definition.
This is only known to fix a bug in the standalone compiler; most
programs should be unaffected. Still, it seems like a good idea.

The blend sampler view is addressed with unnormalized coordinates in the
fragment shader. It should have the same orientation as the surface
does.

Previously, the get table listed all three as having custom locations,
yet find_custom_value did not have cases to handle them.
MAX_VARYING_VECTORS does not need a custom location since MaxVaryings is
already stored as float[4] (or vec4). MaxUniformComponents is stored as
the number of floats, however, so a custom implementation that divides
by 4 is necessary.
Fixes bugs.freedesktop.org #31495.

This fixes incorrect behaviour when the stencil clear value exceeds
the size of the stencil buffer, for example, when set with:
glClearStencil (~1); /* Set a bit pattern of 111...11111110 */
glClear (GL_STENCIL_BUFFER_BIT);
The clear value needs to be masked by the value 2^m - 1, where m is the
number of bits in the stencil buffer. Previously, we passed the value
masked with 0x7fffffff to _mesa_StencilFuncSeparate which then clamps,
NOT masks the value to the range 0 to 2^m - 1.
The result would be clearing the stencil buffer to 0xff, rather than 0xfe.
