If an array redeclaration includes an initializer, the initializer
would previously be dropped on the floor. Instead, directly apply the
initializer to the correct ir_variable instance and append the
generated instructions.
Fixes bugzilla #34374 and piglit tests glsl-{vs,fs}-array-redeclaration.
NOTE: This is a candidate for stable release branches. 0292ffb8 and
8e6cb9fe are also necessary.
Removed sampler view support for USCALED/SSCALED, the texture unit
refuses to convert to non-normalized float. The enums are treated
like UNORM.
Removed duplicate format related headers.
The hw doesn't like it - demos/shadowtex is broken. The emitted shader
isn't totally empty though, the depth write fixup gets emitted instead.
Maybe that one is somewhat fishy, too?

This is an awful hack and will hurt performance on Ironlake, but we're
at a loss as to what's going wrong otherwise. This is the only common
variable we've found that avoids the problem on 4 applications
(CelShading, gnome-shell, Pill Popper, and my GLSL demo), while other
variables we've tried appear to only be confounding. Neither the
specifications nor the hardware team have been able to provide any
enlightenment, despite much searching.

Because the format can be changed to UNORM in a surface.
This fixes:
state_tracker/st_atom_framebuffer.c:163:update_framebuffer_state:
Assertion `framebuffer->cbufs[i]->texture->bind & (1 << 1)' failed.
Computation of the delta of this array from the last had a silly little
bug and ignored any initial delta==0 causing grief in Nexuiz and
friends.

There is a silicon bug which causes unpredictable behaviour if the
URB_FENCE command should cross a cache-line boundary. Pad before the
command to avoid such occurrences. As this command only applies to
gen4/5, do the fixup unconditionally as the specs do not actually state
for which chip it was fixed (and the cost is negligible)...

Previously, the rule deleted by this commit was matched every single
time (being the longest match). If not skipping, it used REJECT to
continue on to the actual correct rule.
The flex manual advises against using REJECT where possible, as it is
one of the most expensive lexer features. So using it on every match
seems undesirable. Perhaps more importantly, it made it necessary for
the #if directive rules to contain a look-ahead pattern to make them
as long as the (now deleted) "skip the whole line" rule.
This patch introduces an exclusive start state, SKIP, to avoid REJECTs.
Each time the lexer is called, the code at the top of the rules section
will run, implicitly switching the state to the correct one.
Fixes piglit tests 16384-consecutive-chars.frag and
16385-consecutive-chars.frag.
The expected result has been out of sync with what glcpp produces for
some time; glcpp's actual result seems to be correct and is very close to
GCC's cpp. Updating this will make it easier to catch regressions in
upcoming commits.
PIPE_BIND_CONSTANT_BUFFER alone was OK for nv50/nvc0, but nv30 will need
to be able to set others on certain chipsets.
