    glsl: Add missing semicolon in the grammar
    
    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.

    glsl: Allow layout qualifiers in GLSL 3.00 ES
    
    Note that while 'packed' is a reserved word in GLSL ES, row_major is not.
    This means that we have to use the string-based matching for that.

    glsl: Create builtin function profiles for GLSL 3.00 ES.
    
    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,
    unpackSnorm2x16, packUnorm2x16, unpackUnorm2x16, packHalf2x16,
    unpackHalf2x16.

    glsl: add determinant() functions.
    
    These functions are defined in GLSL 1.50 and GLES 3.00 ES.
    
    The formulas have been extracted from the existing implementation of
    inverse().

    glsl: Populate built-in types correctly for GLSL 3.00 ES.
    
    This patch implements all of the built-in types for GLSL 3.00 ES.
    This is almost exactly the same as the set of built-in types for GLSL
    1.30, except ate 1D samplers are skipped, and samplerCubeShadow is
    added.
    
    This patch also addes an assertion so that when we add new GLSL
    versions, we'll notice that we need to update the types.
    
    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
        out of its spec."

    glsl: Fix linker checks for GLSL ES 3.00.
    
    This patch updates the following linker checks to do the right thing
    in GLSL 3.00 ES:
    
    - Failing to write to gl_Position is allowed in GLSL 1.40+ as well as
      GLSL 3.00 ES.
    
    - It is an error to write to both gl_ClipVertex and gl_ClipDistance in
      GLSL 1.30+.  This does not apply to GLSL 3.00 ES.
    
    - GLSL 3.00 ES uses the same varying counting rules as GLSL 1.00 ES.
    
    - In GLSL 1.30 and GLSL 3.00 ES, "discard" terminates the shader.
    
    - In GLSL 1.00 ES and GLSL 3.00 ES, both a fragment and a vertex
      shader must be present.

    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.

    instead of doing something special on the first loop iteration.  Suggested by

    glsl: Record in gl_shader whether the shader uses GLSL ES.
    
    Previously we recorded just the GLSL version, with the knowledge that
    100 means GLSL 1.00 ES.  With the advent of GLSL 3.00 ES, this is
    going to get more complex, and eventually will probably become
    ambiguous (GLSL 4.00 already exists, and GLSL 4.00 ES is likely to be
    created some day).
    
    To reduce confusion, this patch simply records whether the shader is
    GLSL ES as an explicit boolean.

    - Integral vertex shader inputs.
    - Range-checking of literal integers.
    - array.length method.

    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.
    
    [v2, idr]: Add PRINTFLIKE annotation to the new method.  The numbering of th
    parameters is correct because GCC is silly.
    
    [v3, idr]: Fix copy-and-paste error in the comment before
    _mesa_glsl_parse_state::is_version.  Noticed by Ken.

    glsl: Make a function to express a GLSL version ir human-readable form.
    
    This will be useful in generating more helpful error messages,
    especially with the addition of GLSL 3.00 ES support.

    glsl: Simplify symbol table version checking.
    
    Previously, we stored the GLSL language version in the
    glsl_symbol_table struct.  But this was unnecessary--all
    glsl_symbol_table needs to know is whether functions and variables
    have separate namespaces (they do in GLSL 1.10 only).

    mesa: Add ARB_ES3_compatibility flag.
    
    Adding this now makes it easier to develop and test GLES3 features, since we
    can do initial development and testing using desktop GL.  Later GLSL compiler
    patches check for either ctx->Extensions.ARB_ES3_compatibility or
    _mesa_is_gles3 to allow certain features (i.e., "#version 300 es").
