GLSL ES does not allow unsized arrays, and GLSL ES 1.00 does not allow
array initializers. However, GLSL ES 3.00 allows array initializers,
and the initializer can explicitly size the array. The specification
even includes some examples of this:
float x[] = float[2] (1.0, 2.0); // declares an array of size 2
float y[] = float[] (1.0, 2.0, 3.0); // declares an array of size 3
float a[5];
float b[] = a;
Move the unsized array check to after the initializer has been
processed. If the array is still unsized, generate the error. This
should have no effect in GLSL ES 1.00 because, as previously mentioned,
array initializers are not allowed.
Fixes piglit "glsl-es-3.00 compiler array-sized-by-initializer.vert".

Newer graphic languages don't want messy float mask results but instead true
"boolean" mask results for float comparisons. Otherwise just need to convert
the floats back to integers. Need to keep the old opcodes however due to both
legacy (gl and d3d9) needing them and because older hw can't really deal with
integers. These new FSEQ/FSGE/FSLT/FSNE opcodes are part of integer API and
hence must be supported if a driver claims to support glsl 1.30 (or
PIPE_SHADER_CAP_INTEGERS).

Because we must maintain an exec_mask even if there's currently nothing
on the mask stack, we can still have an exec_mask at the end of the program.
Effectively, this mask should be set back to default when returning from main.
Without relying on END/RET opcode (I think it's valid to have neither) it is
actually difficult to do this, as there doesn't seem any reasonable place to
do it, so instead let's just say the exec_mask is invalid outside main (which
it really is effectively).
The problem is that geometry shader called end_primitive outside the shader
(in the epilogue), and as a result used a bogus mask, leading to bugs if we
had to set the (somewhat misnamed) ret_in_main bit anywhere. So just avoid
the mask combining function when called from outside the shader.

The code was quite weird, the second comparison was in fact a complete no-op
and we can also do the comparison with the vector directly instead of scalar,
which should not also be faster but it is way more obvious how that mask
is actually going to look like.
Reviewed-by: Zack Rusin <zackr@vmware.com>
Instead of reducing masks to 0/1 simply use the mask directly as -1.
Also use some signed comparison instead of unsigned (as far as I understand
these values have to be (very) small and signed means llvm doesn't have to
apply additional logic to do the unsigned comparisons the cpu can't do).
Saves a couple of instructions in some test geometry shader here.
v2: that was a bit to much optimization, don't skip combining the masks...

Many GLSL shaders contain code of the form:
x = condition ? foo : bar
The compiler emits an ir_if tree for this, since each subexpression
might be a complex tree that could have side-effects and short-circuit
logic operations.
However, the common case is to simply pick one of two constants or
variable's values---which is exactly what SEL is for. Replacing IF/ELSE
with SEL also simplifies the control flow graph, making optimization
passes which work on basic blocks more effective.

The instruction
(+f0.0) SEL dst, src0, src1
will write either src0 or src1 to dst, depending on the predicate.
Unlike most predicated instructions, it always writes to dst.
fs_inst::is_partial_write() is supposed to return true if the whole
register is guaranteed to be written. The !inst->predicated check makes
sense for most instructions, which might not write the whole register,
but SEL is a special case.
This caused live interval analysis to ignore the destination of
predicated SEL instructions when computing "def" information.
Requires the previous commit to avoid regressions.

The existing inst->is_partial_write() already disallows predicated
instructions, so this has no functional change. However, it's worth
doing explicitly since the CSE pass does not consider the flag register.
This means it could blindly factor out operations that use the same
sources, but which have different condition codes set.
This prevents a regression in the next commit.

Usually, the driver creates both 8-wide and 16-wide variants of every

warning explaining why only an 8-wide program exists.
However, when there are pull parameters, the driver won't even bother
trying the 16-wide compile (since it would fail). In this case, it
failed to emit a performance warning, leaving no explanation for the
missing 16-wide program.

Fix ilo_gpe_init_view_surface_for_buffer to allow buffer to be NULL, and add
ilo_gpe_set_view_surface_bo to set it later. This allows us to set up
SURFACE_STATE early for constant buffers backed by user buffers.
In finalize_index_buffer(), when the current index buffer was destroyed due to
u_upload_data(), it may happen that the new index buffer is at the same
address as the old one. Comparing the pointers to the two buffers could fail
to work, and 3DSTATE_INDEX_BUFFER would be incorrectly skipped.
Holding a reference to the current index buffer before calling u_upload_data()
should fix the problem.

d3d10 has no notion of distinct array resources neither at the resource nor
sampler view level. However, shader dcl of resources certainly has, and
d3d10 expects resinfo to return the values according to that - in particular
a resource might have been a 1d texture with some array layers, then the
sampler view might have only used 1 layer so it can be accessed both as 1d
or 1d array texture (I think - the former definitely works). resinfo of a
resource decleared as array needs to return number of array layers but
non-array resource needs to return 0 (and not 1). Hence fix this by passing
the target from the shader decl to emit_size_query and use that (in case of
OpenGL the target will come from the instruction itself).
Could probably do the same for actual sampling, though it may not matter there
(as the bogus components will essentially get clamped away), possibly could
wreak havoc though if it REALLY doesn't match (which is of course an error
but still).

From context it is clear that values greater than 1.0 should only
generate an INVALID VALUE error in a forward-compatible context.
The code was correctly quoting this spec text, but it was disallowing
all line widths in forward-compatible contexts, instead of just widths
greater than 1.0.
This patch introduces the correct check, so that setting a line width
