glsl: Refresh autogenerated lexer and parser files.
For the last three commits.
Kenneth Graunke [Sun, 14 Nov 2010 07:09:43 +0000 (23:09 -0800)]
glsl: Add support for the 'u' and 'U' unsigned integer suffixes.
Kenneth Graunke [Sun, 14 Nov 2010 06:02:09 +0000 (22:02 -0800)]
glsl: Add new keywords and reserved words for GLSL 1.30.

glsl: Rework reserved word/keyword handling in the lexer.
This consolidates the TOKEN_OR_IDENTIFIER and RESERVED_WORD macros into
a single KEYWORD macro.
The old TOKEN_OR_IDENTIFIER macros handled the case of a word going from
an identifier to a keyword; the RESERVED_WORD macro handled a word going
from a reserved word to a language keyword. However, neither could
properly handle samplerBuffer (for example), which is an identifier in
1.10 and 1.20, a reserved word in 1.30, and a keyword in 1.40 and on.
Furthermore, the existing macros didn't properly handle reserved words
in GLSL ES 1.00. The best they could do was return a token (rather than
an identifier), resulting in an obtuse parser error, rather than a
user-friendly "you used a reserved word" error message.

glsl: Convert glsl_type::base_type from #define'd constants to an enum.
This is nice because printing type->base_type in GDB will now give you a
readable name instead of a number.
Kenneth Graunke [Thu, 11 Nov 2010 07:14:45 +0000 (23:14 -0800)]
glsl: Remove GLSL_TYPE_FUNCTION define.
Functions are not first class objects in GLSL, so there is never a value
of function type. No code actually used this except for one function
which asserted it shouldn't occur. One comment mentioned it, but was
incorrect. So we may as well remove it entirely.

r600g: Add PIPE_FORMAT_L8A8_UNORM for Evergreen as well.
Henri Verbeet [Mon, 15 Nov 2010 21:18:12 +0000 (22:18 +0100)]
r600: Evergreen has two extra frac_bits for the sampler LOD state.
Note: this is a candidate for the 7.9 branch.
