I erroneously added this back in January 2011 in commit 88421589.
Looking at the commit message, I have no idea why I added it. It only
added non-array structure fields to the symbol table, so array structure
fields are treated correctly.
Fixes piglit tests structure-and-field-have-same-name.vert and
structure-and-field-have-same-name-nested.vert. It should also fix
WebGL conformance tests shader-with-non-reserved-words.
NOTE: This is a candidate for the stable release branches.

This may not be strictly necessary, but every other rule in the grammar ends
with a semicolon. It also appears that this was supposed to be commited with
the original patch that changed this rule, but the wrong version of the patch
was accidentally pushed.

Version directive handling is going to have to be used within two
parser rules, one for desktop-style version directives (e.g. "#version
130") and one for the new ES-style version directive (e.g. "#version
300 es"), so this patch moves it to a function that can be called from
both rules.
No functional change.

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.

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).").

The previous implementation required a flag in _mesa_glsl_parse_state
and line of code to initialize it for every version of the shading
language we intend to support. As we look to add 150, 330, 400, 410,
420, and beyond, this gets rather unwieldy.
This patch retains the switch statement (to reject, say, #version 111),
but removes all the bits. Code to check for ctx->API == API_OPENGL_CORE
could easily be added to the 110 and 120 cases to reject those.
v2: Use _mesa_is_desktop_gl to preserve the existing behavior in the
presence of the new API_OPENGL_CORE enumeration.

It was using state->Const.GLSL_100ES, which is set if the driver
supports ARB_ES2_compatibility or we're in ES2 mode. Instead, it should
use state->language_version, as that represents the actual GLSL version
of the shader being compiled.
Since the correct logic is < 120 && !100, just make it == 110.

This adds index support to the GLSL compiler.
I'm not 100% sure of my approach here, esp without how output ordering
happens wrt location, index pairs, in the "mark" function.
Since current hw doesn't ever have a location > 0 with an index > 0,
we don't have to work out if the output ordering the hw requires is
location, index, location, index or location, location, index, index.
But we have no hw to know, so punt on it for now.
v2: index requires layout - catch and error
setup explicit index properly.
v3: drop idx_offset stuff, assume index follow location

The samplerBuffer type will be undefined in !glsl 1.40, and the
keyword is marked as reserved. The [iu]samplerBuffer types are not
marked as reserved pre-1.40, so they don't have separate tokens and
fall through to normal type handling.

Invalid shaders containing the character % at an unexpected location
would cause Bison to call yyerror with a message of:
syntax error, unexpected '%'
Bison expects yyerror() to take a string, while _mesa_glsl_error() is a
printf-style function. This hit the classic printf string escape issue:
_mesa_glsl_error(loc, state, "unexpected '%'"); // invalid!
_mesa_glsl_error(loc, state, "%s", "unexpected '%'"); // correct.
This caused assertion failures after ralloc_asprintf_append called
vsnprintf to determine the length of the text that would be printed:
vsnprintf would see the invalid format and return -1, an invalid length.
The solution is to define a proper yyerror() wrapper function that calls
_mesa_glsl_error with the "%s". Since we compile with -p "_mesa_glsl",
yyerror is defined as:
#define yyerror _mesa_glsl_error
So we have to #undef yyerror in order to be able to declare it.

We now tie the grammar to the ctors of the ASTs they reference.
This requires that we actually have definitions of the ctors.
In addition, we also need to define "print" and "hir" methods for the AST
classes. The Print methods are pretty simple to flesh out. However, at this
stage of the development, we simply stub out the "hir" methods and flesh
them out later.
Also, since actual class instances get returned by the productions in the
grammar, we also need to designate the type of the productions that
reference those instances.

The grammar is modified to support switch statements. Rather than follow the
grammar in the appendix, which allows case labels to be placed ANYWHERE
as a regular statement, we follow the development of the grammar as
described in the body of the GLSL spec.
In this variation, the switch statement has a body which consists of a list
of case statements. A case statement is preceded by a list of case labels and
ends with a list of statements.
