with
the original patch that changed this rule, but the wrong version of the

Nearly all of the builtin functions in GLSL 3.00 ES are already
implemented in Mesa; this patch enables them.
A few functions are not implemented yet; those have been commented
out, with a FIXME comment to act as a reminder of what still needs to
be implemented. Here is the complete list: packSnorm2x16,

This is almost exactly the same as the set of built-in types for GLSL

This patch also addes an assertion so that when we add new GLSL

In review, Eric noted:
"This change looks correct. The overall interaction of profiles is
getting ugly, though. I'm imagining a restructure of the symbol
table population so that there's a big list of types, and each
#version has a nice list of strings of type names copy and pasted

glsl: Clean up shading language mixing check for GLSL 3.00 ES.
Previously, we prohibited mixing of shading language versions if
min_version == 100 or max_version >= 130. This was technically
correct (since desktop GLSL 1.30 and beyond prohibit mixing of shading
language versions, as does GLSL 1.00 ES), but it was confusing. Also,
we asserted that all shading language versions were between 1.00 and
1.40, which was unnecessary (since the parser already checks shading
language versions) and doesn't work for GLSL 3.00 ES.
This patch changes the code to explicitly check that (a) ES shaders
aren't mixed with desktop shaders, (b) shaders aren't mixed between ES
versions, and (c) shaders aren't mixed between desktop GLSL versions
when at least one shader is GLSL 1.30 or greater. Also, it removes
the unnecessary assertion.

glsl: parse GLSL ES 3.00 keywords correctly.
GLSL ES 3.00 adds the following keywords over GLSL 1.00: uint,
uvec[2-4], matNxM, centroid, flat, smooth, various samplers, layout,
switch, default, and case.
Additionally, it reserves a large number of keywords, some of which
were already reserved in versions of desktop GL that Mesa supports,
some of which are new to Mesa.
A few of the reserved keywords in GLSL ES 3.00 are keywords that are
supported in all other versions of GLSL: attribute, varying,
sampler1D, sampler1DShador, sampler2DRect, and sampler2DRectShadow.
This patch updates the lexer to handle all of the new keywords
correctly when the language being parsed is GLSL 3.00 ES.

glsl: Rework lexer keyword handling in preparation for GLSL 3.00 ES.
This patch expands the lexer KEYWORD macro to take two additional
arguments: the GLSL ES versions in which the given keyword was first
reserved, and supported, respectively. This will allow us to
trivially add support for GLSL 3.00 ES keywords, even though the set
of GLSL 3.00 ES keywords is neither a subset or a superset of the
keywords corresponding to any desktop GLSL version.
The new KEYWORD macro makes use of the
_mesa_glsl_parse_state::is_version() function, so it accepts 0 as
meaning "unsupported" (rather than 999, which we used previously).
Note that a few keywords ("packed" and "row_major") are supported
*either* when GLSL 1.40 is in use or when ARB_uniform_buffer_obj
support is enabled. Previously, we handled these by cleverly taking
advantage of the fact that the KEYWORD macro didn't parenthesize its
arguments in the usual way. Now they are handled more
straightforwardly, with a new macro, KEYWORD_WITH_ALT.

glsl: Make use of new _mesa_glsl_parse_state::check_version() function.
Previous to this patch, we were not very consistent about the errors
we generate when a shader tried to use a feature that is prohibited in
the current GLSL version. Some error messages failed to mention the
GLSL version currently in use (or did so inaccurately), and some error
messages failed to mention the first GLSL version in which the given
feature is allowed.
This patch reworks all of the error checks to use the check_version()
function, which produces error messages in a standard form
(approximately "$FEATURE forbidden in $CURRENT_GLSL_VERSION
($REQUIRED_GLSL_VERSION required).").

glsl: Add GLSL version query functions.
With the advent of GLSL 3.00 ES, the version checks we perform in the
GLSL compiler (to determine which language features are present) will
become more complicated. To reduce the complexity, this patch adds
functions check_version() and is_version() to _mesa_glsl_parse_state.
These functions take two version numbers: a desktop GLSL version and a
GLSL ES version, and return a boolean indicating whether the GLSL
version being compiled is at least the required version. So, for
example, is_version(130, 300) returns true if the GLSL version being
compiled is at least desktop GLSL 1.30 or GLSL 3.00.
The check_version() function additionally produces an error message if
the version check fails, informing the user of which GLSL version(s)
support the given feature.
