There is a piece of code that is trying to match expressions of the
form (mul (floor (add (abs x) 0.5) (sign x))). However the check for
the add expression wasn't checking whether it had the expected
operation. It looks like this was just an oversight because it doesn't
match the pattern for the rest of the code snippet. The existing line
to check whether add_expr!=NULL was added as part of a coverity fix in
3384179f.

We already don't convert constants out of SSA, and in our backend we'd
like to have only one way of saying something is still in SSA.
The one tricky part about this is that we may now leave some undef
instructions around if they aren't part of a phi-web, so we have to be
more careful about deleting them.

Patch provides new compiler option for backend to force unroll loops
that have non-constant expression indexing on sampler arrays.
This makes sure that we can never end up with a shader that uses loop
induction variable as sampler array index but does not unroll because
of having too much instructions. This would not work without dynamic

_mesa_strtod and _mesa_strtof are only used from the GLSL compiler and
the ARB_[vertex|fragment]_program code, meaning that the locale doesn't
need to be initialized before the first OpenGL context gets initialized.
So let's use explicit initialization from the one-time init code instead
of depending on a C++ compiler to initialize at image-load time.

This reverts commit c2ff3485b3.
Ilia and I noticed a memory leak caused by this patch: at least with
fixed-function programs, we clone things using ProgramResourceList as
the context before reralloc makes it non-NULL.
I believe Tapani found other bugs with these patches, so I'm just going
to revert them for now and let him pursue them further.
We already recognize min(max(a, 0.0), 1.0) as a saturate, but neglected
this variant (which is also handled by the GLSL IR pass).

These are basically just moves, so they should be safe as well.
When disabling i965's GLSL IR level scalarizer (channel expressions)
pass, I started seeing NIR code like this:
if ssa_21 {
block block_1:
/* preds: block_0 */
vec4 ssa_120 = vec4 ssa_82, ssa_83, ssa_84, ssa_30
/* succs: block_3 */
} else {
block block_2:
/* preds: block_0 */
/* succs: block_3 */
}
block block_3:
/* preds: block_1 block_2 */
vec4 ssa_33 = phi block_1: ssa_120, block_2: ssa_2
Previously, the GLSL IR scalarizer pass would break the vec4 into a
series of fmovs, which were allowed by the peephole pass. But with
the vec4 operation, they were not. We want to keep getting selects.

It's not totally clear whether other Mesa drivers can safely cope with
over-sized UBOs, but at least for llvmpipe receiving a UBO larger than
its limit causes problems, as it won't fit into its internal display
lists.
This fixes piglit "arb_uniform_buffer_object-maxuniformblocksize
fsexceed" without regressions for llvmpipe.
NVIDIA driver also fails to link the shader from
"arb_uniform_buffer_object-maxuniformblocksize fsexceed".

PS: I don't recommend cherry-picking this for Mesa stable, as some app
might inadvertently been relying on UBOs larger than
GL_MAX_UNIFORM_BLOCK_SIZE to work on other drivers, so even if this
commit is universally accepted it's probably best to let it mature in
master for a while.

Without this patch, the following constructs (not an extensive list)
would crash mesa:
- mat2 foo = mat2(1); vec4 bar = vec4(foo);
- mat3 foo = mat3(1); vec4 bar = vec4(foo);
- mat3 foo = mat3(1); ivec4 bar = ivec4(foo);
The first case is explicitely allowed by the GLSL spec, as seen on
page 101 of the GLSL 4.40 spec:
"vec4(mat2) // the vec4 is column 0 followed by column 1"
The other cases are implicitely allowed also.
The actual changes are quite minimal. We first split each column of
the matrix to a list of vectors and then use them to initialize the
vector. An additional check to make sure that we are not trying to
copy 0 elements of a vector fix the (i)vec4(mat3) case as the last
vector (3rd column) is not needed at all.
