* glsl: Record in gl_shader whether the shader uses GLSL ES.Paul Berry2012-12-061-0/+1
| | | | | | | | | | | | | | | | | | 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. [v2, idr]: s/IsEs(Shader|Prog)/IsES/ Suggested by Ken and Eric.

* glsl/parser: Extract version directive processing into a function.Paul Berry2012-12-063-42/+55
| | | | | | | | | | | | | | 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.

* 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.

* glcpp: Rewrite line-continuation support to act globally.Carl Worth2012-11-301-66/+43
| | | | | | | | | | | | | | | | | Previously, we were only supporting line-continuation backslash characters within lines of pre-processor directives, (as per the specification). With OpenGL 4.2 and GLES3, line continuations are now supported anywhere within a shader. While changing this, also fix a bug where the preprocessor was ignoring line continuation characters when a line ended in multiple backslash characters. The new code is also more efficient than the old. Previously, we would perform a ralloc copy at each newline. We now perform copies only at each occurrence of a line-continuation.

(Note that this test is distinct from test 059-token-pasting-integer which pastes integers parsed from the source. Those are parsed to INTEGER_STRING tokens and are already pasted correctly as verified by that test.
