From the OpenGL docs for GL_ARB_explicit_attrib_location:
This extension provides a method to pre-assign attribute locations to
named vertex shader inputs and color numbers to named fragment shader
outputs.
This was accidentally implemented for fragment shader inputs. This
patch fixes it to apply to fragment shader outputs.

Lots of code (deleted by this patch) tried to make type == result->type,
but not all cases did. Don't pretend; just use result->type.

The expression

The warning is only emitted for the left-hand operands, becuase the

By always using a boolean, we should generally avoid further
complaints. The failure case I see is logic_not, where the user might
understandably make the mistake of using `!' on a boolean vector (like
a piglit case did recently!), and then get a further complaint that
the new boolean type doesn't match the bvec it gets assigned to.

ends up in an expression and ir_constant_expression gets angry).

GLSL 1.30 states clearly that only float and int are allowed, while the

take precision qualifiers.

The rvalue of the returned value can be NULL if the shader says
'return foo();' and foo() is a function that returns void.
Existing GLSL specs do *NOT* say that this is an error. The type of
the return value is void. If the return type of the function is also
void, then this should compile without error. I expect that future
versions of the GLSL spec will fix this (wink, wink, nudge, nudge).

The specs that add 'layout' require the use of 'in' or 'out'.
However, a number of implementations, including Mesa, shipped several
of these extensions allowing the use of 'varying' and 'attribute'.
For these extensions only a warning is emitted.
This differs from the behavior of Mesa 7.10. Mesa 7.10 would only
accept 'attribute' with 'layout(location)'. This behavior was clearly
wrong. Rather than carrying the broken behavior forward, we're just
doing the correct thing.
This is related to (piglit) bugzilla #31804.
NOTE: This is a candidate for the 7.9 and 7.10 branches.
All of the extensions that add the 'layout' keyword also enable (and

variable invariant.

but a warning is generated.

GLSL 1.10 and 1.20 allow any sort of sampler array indexing.
Restrictions were added in GLSL 1.30. Commit f0f2ec4d added support
for the 1.30 restrictions, but it broke some valid 1.10/1.20 shaders.
This changes the error to a warning in GLSL 1.10, GLSL 1.20, and GLSL
ES 1.00.
There are some spurious whitespace changes in this commit. I changed
the layout (and wording) of the error message so that all three cases
would be similar. The 1.10/1.20 and 1.30 text is the same. The only
difference is that one is an error, and the other is a warning. The
GLSL ES 1.00 wording is similar but not quite the same.

See section 4.3.7 of the GLSL 1.30 spec.
I think was used long ago, when we actually read the builtins into the
shader's instruction stream directly, rather than creating a separate
shader and linking the two. It doesn't seem to serve any purpose now.
do_assignment may apply implicit conversions to coerce the base type

Raise error if a sampler array is indexed with a non-constant expression.
From section 4.1.7 of the GLSL 1.30 spec:
"Samplers aggregated into arrays within a shader (using square
brackets [ ]) can only be indexed with integral constant
expressions [...]."
Types of declared variables and their initializer must match excatly
except for unsized arrays. Previously the type inherritance for
unsized arrays happened implicitly in the emitted assignment.
However, this assignment is never emitted for uniforms. Now that type
is explicitly copied unconditionally.

By not doing so, the uniform contents of
glsl-uniform-non-uniform-array-compare.shader_test was getting thrown
out since nobody was recorded as dereferencing the array.
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.
