1. We can't turn an instruction into a presubtract operation if it
writes to one of the registers it reads from.
2. If we turn an instruction into a presubtract operation, we can't
remove that intruction unless all readers can use the presubtract
operation.
This fixes fdo bug 30337.
This is a candidate for the 7.9 branch.
(cherry picked from commit 522e994a22)
TX_BORDER_COLOR should be formatted according to the texture format.
Also the interaction with ARB_texture_swizzle should be fixed too.
NOTE: This is a candidate for the 7.9 branch.
(cherry picked from commit 9f35dcd24c)
This commit fixes an infinite loop in foreach_s if remove_from_list is used
more than once on the same item with other list operations in between.
NOTE: This is a candidate for the 7.9 branch because the commit
"r300g: fixup long-lived BO maps being incorrectly unmapped when flushing"
depends on it.
(cherry picked from commit 68afbe89c7)
Make libr300compiler.a a PHONY target so that this library will always be
built. This fixes the problem of libr300compiler.a not being updated
when r300g is being built and r300c is not.

Fix commit e7087175f8. Move the reference to
GL_VERSION_2_1_functions to intel_extensions.c where it's available,
don't try to enable a non-existing extension and advertise 1.20 for all
intel chipsets, not just GEN4 and up.
(cherry picked from commit b91dba49e0)
Instead of using the invalid GL_ARB_shading_language_120 extension to
determine the GLSL version, use a new ctx->Const.GLSLVersion field.
Updated the intel and r600 drivers, but untested.
See fd.o bug 29910
NOTE: This is a candidate for the 7.9 branch (but let's wait and see if
there's any regressions).

When ir_binop_all_equal and ir_binop_any_nequal were introduced, the
meaning of these two opcodes changed to return vectors rather than a
single scalar, but the constant expression handling code was incorrectly
written and only worked for scalars. As a result, only the first
component of the returned vector would be properly initialized.

Such as: "ir_validate.cpp:143: warning: format ‘%p’ expects type ‘void*’,
but argument 2 has type ‘ir_variable*’"
(cherry picked from commit 1739124159)
Those have the callee field set to the null pointer, so
calling the public constructor will segfault.

Fixes this GCC warning.

(cherry picked from commit a822ae3f1a)
Currenly GLSL happily generates indirect addressing of any kind of
arrays.
Unfortunately DirectX 9 GPUs are not guaranteed to support any of them in
general.
This pass fixes that by lowering such constructs to a binary search on the
values, followed at the end by vectorized generation of equality masks, and
4 conditional assignments for each mask generation.
Note that this requires the ir_binop_equal change so that we can emit SEQ
to generate the boolean masks.
Unfortunately, ir_structure_splitting is too dumb to turn the resulting
constant array references to individual variables, so this will need to
be added too before this pass can actually be effective for temps.
Several patches in the glsl2-lower-variable-indexing were squashed
into this commit. These patches fix bugs in Luca's original
implementation, and the individual patches can be seen in that branch.
This was done to aid bisecting in the future.

Fix the following GCC warning.

Some pathological triangles cause a theoritically impossible number of
clipped vertices.
The clipper will still assert, but at least release builds will not
crash, while this problem is further investigated.
This is required by the spec, so respect that.
(oh, and it was required to actually fix occlusion-query-discard,
though I didn't know at the time of the commit since o-q-discard was
hanging the GPU)
(cherry picked from commit 4a0bc4716d)
Looks like the problem was we weren't passing the depth to the render
target as expected, so the chip would wedge. Fixes GPU hang in
occlusion-query-discard.
Bug #30097
(cherry picked from commit dd9a88f4dd)
We can't expect to have a context when this is called, and we don't need one
so just require a __DRIscreen instead.
