* glsl/sso: Add parser and AST-to-HIR support for separate shader object layoutsIan Romanick2014-02-211-0/+17
| | | | | | | | | | | | GL_ARB_separate_shader_objects adds the ability to specify location layouts for interstage inputs and outputs. In addition, this extension makes 'in' and 'out' generally available for shader inputs and outputs. This mimics the behavior of GL_ARB_explicit_attrib_location.

* glsl: convert GS input primitive to use ast_type_qualifierJordan Justen2014-02-201-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | We introduce a new merge_in_qualifier ast_type_qualifier which allows specialized handling of merging input layout qualifiers. By merging layout qualifiers into state->in_qualifier, we allow multiple input qualifiers. For example, the primitive type can be specified specified separately from the invocations count (ARB_gpu_shader5). state->gs_input_prim_type is moved into state->in_qualifier->prim_type state->gs_input_prim_type_specified is still processed separately so we can determine when the input primitive is specified. This is important since certain scenerios are not supported until after the primitive type has been specified in the shader code. v4: * Merge with compute shader input layout qualifiers Signed-off-by: Jordan Justen <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we had an enum called gl_shader_type which represented pipeline stages in the order they occur in the pipeline (i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several inconsistently named functions for converting between it and other representations: - _mesa_shader_type_to_string: gl_shader_type -> string - _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type - _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type - _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string This patch tries to clean things up so that we use more consistent terminology: the enum is now called gl_shader_stage (to emphasize that it is in the order of pipeline stages), and the conversion functions are: - _mesa_shader_stage_to_string: gl_shader_stage -> string - _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage - _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage - _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES, for consistency with the new name for the enum.

* Rename overloads of _mesa_glsl_shader_target_name().Paul Berry2013-12-301-3/+4
| | | | | | | | | | | | Previously, _mesa_glsl_shader_target_name() had an overload for GLenum and an overload for the gl_shader_type enum, each of which behaved differently. However, since GLenum is a synonym for unsigned int, and unsigned ints are often used in place of gl_shader_type (e.g. in loop indices), there was a big risk of calling the wrong overload by mistake. This patch gives the two overloads different names so that it's always clear which one we mean to call. Reviewed-by: Brian Paul <[email protected]>

* glsl: Simplify the built-in function linking code.Kenneth Graunke2013-12-011-3/+1
| | | | | | | | | | | | | | | | | | Previously, we stored an array of up to 16 additional shaders to link, as well as a count of how many each shader actually needed. Since the built-in functions rewrite, all the built-ins are stored in a single shader. So all we need is a boolean indicating whether a shader needs to link against built-ins or not. During linking, we can avoid creating the temporary array if none of the shaders being linked need built-ins. Otherwise, it's simply a copy of the array that has one additional element. This is much simpler. This patch saves approximately 128 bytes of memory per gl_shader object. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

| | | | | | | | | | | | | | | The _mesa_glsl_parse_state object relies on the memory allocator zeroing out its contents before it's initialized, which is quite an unusual practice in the C++ world because it ties objects to some specific allocation scheme, and gives unpredictable results when an object is created with a different allocator -- Stack allocation, array allocation, or aggregation inside a different object are some of the useful possibilities that come to my mind.

* glsl: Implement rules for geometry shader input sizes.Paul Berry2013-08-011-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section 4.3.8.1 (Input Layout Qualifiers) of the GLSL 1.50 spec contains some tricky rules for how the sizes of geometry shader input arrays are related to the input layout specification. In essence, those rules boil down to the following: - If an input array declaration does not specify a size, and it follows an input layout declaration, it is sized according to the input layout. - If an input layout declaration follows an input array declaration that didn't specify a size, the input array declaration is given a size at the time the input layout declaration appears. - All input layout declarations and input array sizes must ultimately match. Inconsistencies are reported as soon as they are detected, at compile time if the inconsistency is within one compilation unit, otherwise at link time. - At least one compilation unit must contain an input layout declaration.

* glsl: Fix unsupported version error for GLSL ES 3.00, future proof for 3.30.Paul Berry2013-02-121-0/+6
| | | | | | | | | | | | | | | | | | | | | | 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.
