* glsl: Enable GLSL ES 3.00 features inherited from desktop GLSL.Paul Berry2012-12-065-17/+47
| | | | | | | | | | | | | | | | | | | | This patch turns on the following features for GLSL ES 3.00: - Array constructors, whole array assignment, and array comparisons. - Second and third operands of ?: may be arrays. - Use of "in" and "out" qualifiers on globals. - Bitwise and modulus operators. - Integral vertex shader inputs. - Range-checking of literal integers. - array.length method. - Function calls may be constant expressions. - Integral varyings must be qualified with "flat". - Interpolation and centroid qualifiers may not be applied to vertex shader inputs.

* glsl: parse GLSL ES 3.00 keywords correctly.Paul Berry2012-12-062-78/+114
| | | | | | | | | | | | | | | | | | | | | 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.Paul Berry2012-12-061-132/+136
| | | | | | | | | | | | | | | | | | | | | | | | 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.Paul Berry2012-12-065-74/+50
| | | | | | | | | | | | | | | | | | 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.Paul Berry2012-12-062-10/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* android: Fix build of libmesa_programChad Versace2012-12-051-0/+3
| | | | | | | | | | | | | | | | | Commit 4097308 fixed the build in a questionable way. It worked at the time, but, as Ian pointed out, the fix would likely fail at a future commit due to the indeterminism of parallel builds. And that's exactly what happened; the fix no longer works. `mm -j4` on Fedora 17 fails for me. The problem is that there is no rule for program_parse.tab.h. To fix that, this patch adds a rule that makes program_parse.tab.c depend on program_parse.tab.h. Technically, the c file does not depend on the h file. However, because the two files are generated together by a single invocation of Bison, any rule that forces execution of Bison is sufficient. Signed-off-by: Chad Versace <[email protected]>

* i965/fs: Add support for uniform array access with a variable index.Eric Anholt2012-12-044-24/+216
| | | | | | | | | | | | | Serious Sam 3 had a shader hitting this path, but it's used rarely so it didn't show a significant performance difference (n=7). It does reduce compile time massively, though -- one shader goes from 14s compile time and 11723 instructions generated to .44s and 499 instructions. Note that some shaders lose 16-wide mode because we don't support 16-wide and pull constants at the moment (generally, things looping over a few-element array where the loop isn't getting unrolled). Given that those shaders are being generated with 15-20% fewer instructions, it probably outweighs the loss of 16-wide.
