* glsl: Fix error checking on "flat" keyword to match GLSL ES 3.00, GLSL 1.50.Paul Berry2013-02-131-16/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All of the GLSL specs from GLSL 1.30 (and GLSL ES 3.00) onward contain language requiring certain integer variables to be declared with the "flat" keyword, but they differ in exactly *when* the rule is enforced: (a) GLSL 1.30 and 1.40 say that vertex shader outputs having integral type must be declared as "flat". There is no restriction on fragment shader inputs. (b) GLSL 1.50 through 4.30 say that fragment shader inputs having integral type must be declared as "flat". There is no restriction on vertex shader outputs. (c) GLSL ES 3.00 says that both vertex shader outputs and fragment shader inputs having integral type must be declared as "flat". Previously, Mesa's behaviour was consistent with (a). This patch makes it consistent with (b) when compiling desktop shaders, and (c) when compiling ES shaders. Rationale for desktop shaders: once we add geometry shaders, (b) really seems like the right choice, because it requires "flat" in just the situations where it matters. Since we may want to extend geometry shader support back before GLSL 1.50 (via ARB_geometry_shader4), it seems sensible to apply this rule to all GLSL versions. Also, this matches the behaviour of the nVidia proprietary driver for Linux, and the expectations of Intel's oglconform test suite. Rationale for ES shaders: since the behaviour specified in GLSL ES 3.00 matches neither pre-GLSL-1.50 nor post-GLSL-1.50 behaviour, it seems likely that this was a deliberate choice on the part of the GLES folks to be more restrictive. Also, the argument in favor of (b) doesn't apply to GLES, since it doesn't support geometry shaders at all. Some discussion about this has already happened on the Mesa-dev list.

* glsl: don't allow non-flat integral types in varying structs/arrays.Paul Berry2013-02-133-6/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the GLSL 1.30 spec, section 4.3.6 ("Outputs") says: "If a vertex output is a signed or unsigned integer or integer vector, then it must be qualified with the interpolation qualifier flat." The GLSL ES 3.00 spec further clarifies, in section 4.3.6 ("Output Variables"): "Vertex shader outputs that are, *or contain*, signed or unsigned integers or integer vectors must be qualified with the interpolation qualifier flat." (Emphasis mine.) The language in the GLSL ES 3.00 spec is clearly correct and should be applied to all shading language versions, since varyings that contain ints can't be interpolated, regardless of which shading language version is in use. (Note that in GLSL 1.50 the restriction is changed to apply to fragment shader inputs rather than vertex shader outputs, to accommodate the fact that in the presence of geometry shaders, vertex shader outputs are not necessarily interpolated. That will be addressed by a future patch). NOTE: This is a candidate for stable branches. Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>
* glsl: Allow default precision qualifiers to be set for sampler types.Paul Berry2013-02-131-3/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | From GLSL ES 3.00 section 4.5.4 ("Default Precision Qualifiers"): "The precision statement precision precision-qualifier type; can be used to establish a default precision qualifier. The type field can be either int or float or any of the sampler types, and the precision-qualifier can be lowp, mediump, or highp." GLSL ES 1.00 has similar language. GLSL 1.30 doesn't allow precision qualifiers on sampler types, but this seems like an oversight (since the intention of including these in GLSL 1.30 is to allow compatibility with ES shaders). Previously, Mesa followed GLSL 1.30 and only allowed default precision qualifiers to be set for float and int. This patch makes it follow GLSL ES rules in all cases. Fixes Piglit tests default-precision-sampler.{vert,frag}. Partially addresses https://bugs.freedesktop.org/show_bug.cgi?id=60737. NOTE: This is a candidate for stable branches.

* glsl: Fix unsupported version error for GLSL ES 3.00, future proof for 3.30.Paul Berry2013-02-122-54/+64
| | | | | | | | | | | | | | | | | | | | | | When the user specifies an unsupported GLSL version, _mesa_glsl_parse_state::process_version_directive() nicely gives them an error message telling them which GLSL versions are supported. Previous to this patch, the logic for determining whether a given language version was supported was independent from the logic to generate this error message string; as a result, we had a bug where GLSL 3.00 would never be listed in the error message as an available language version, even if it was really available. To make matters worse, the code for generating the error message string assumed that desktop GL versions were always separated by 0.10, an assumption that will be wrong as soon as we support GLSL 3.30. This patch fixes both problems by adding a table of supported GLSL versions to _mesa_glsl_parse_state; this table is used both to generate the error message and to check whether a given version is supported.

* glsl: Support transform feedback of varying structs.Paul Berry2013-02-042-67/+184
| | | | | | | | | | | | | | | | | | | Since transform feedback needs to be able to access individual fields of varying structs, we can no longer match up the arguments to glTransformFeedbackVaryings() with variables in the vertex shader. Instead, we build up a hashtable which records information about each possible name that is a candidate for transform feedback, and then match up the arguments to glTransformFeedbackVaryings() with the contents of that hashtable. Populating the hashtable uses the program_resource_visitor infrastructure, so the logic is shared with how we handle uniforms. NOTE: This is a candidate for the 9.1 branch.

* glsl: Use parse_program_resource_name to parse transform feedback varyings.Paul Berry2013-02-042-19/+16
| | | | | | | | | | | | | | | | | | | Previously, transform feedback varyings were parsed in an ad-hoc fashion that wasn't compatible with structs (or array of structs). This patch makes it use parse_program_resource_name(), which correctly handles both. Note that parse_program_resource_name()'s technique for handling mal-formed input strings is to simply let them through and rely on the fact that a future name lookup will fail. Because of this, tfeedback_decl::init() no longer needs to return a boolean error code--it always succeeds, and if the input was mal-formed the error will be detected later.

More generally, not honoring CFLAGS is bad. Automake is evidently too stupid to accept if CROSS_COMPILING CC = @CC_FOR_BUILD@ ... else CC = @CC@ endif without warning that CC has been already defined. The warnings are harmless, but I'd prefer to avoid future reports about them, so define proxy variables, which are assigned inside the conditional and then unconditionally assigned to CC et al.
