* glcpp: Set extension defines after resolving the GLSL version.Matt Turner2014-01-233-143/+172
| | | | | | | | | | | | | | | | | | | | | | Instead of defining preprocessor macros in glcpp_parser_create based on the GL API, wait until the shader version has been resolved. Doing this allows us to correctly set (and not set) preprocessor macros for extensions allowed by the API but not the shader, as in the case of ARB_ES3_compatibility. The shader version has been resolved when the preprocessor encounters the first preprocessor token, since the GLSL spec says "The #version directive must occur in a shader before anything else, except for comments and white space." Specifically, if a #version token is found the version is known explicitly, and if any other preprocessor token is found then the GLSL version is implicitly 1.10.

* glsl: Simplify aggregate type inference to prepare for ARB_arrays_of_arrays.Paul Berry2014-01-225-148/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the time it is not necessary to perform type inference to compile GLSL; the type of every expression can be inferred from the contents of the expression itself (and previous type declarations). The exception is aggregate initializers: their type is determined by the LHS of the variable being assigned to. For example, in the statement: mat2 foo = { { 1, 2 }, { 3, 4 } }; the type of { 1, 2 } is only known to be vec2 (as opposed to, say, ivec2, uvec2, int[2], or a struct) because of the fact that the result is being assigned to a mat2. Previous to this patch, we handled this situation by doing some type inference during parsing: when parsing a declaration like the one above, we would call _mesa_set_aggregate_type(), which would infer the type of each aggregate initializer and store it in the corresponding ast_aggregate_initializer::constructor_type field. Since this happened at parse time, we couldn't do the type inference using glsl_type objects; we had to use ast_type_specifiers, which are much more awkward to work with. Things are about to get more complicated when we add support for ARB_arrays_of_arrays. This patch simplifies things by postponing the call to _mesa_set_aggregate_type() until ast-to-hir time, when we have access to glsl_type objects. As a side benefit, we only need to have one call to _mesa_set_aggregate_type() now, instead of six. Reviewed-by: Matt Turner <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling function calls, we often want to walk through the list of formal parameters and list of actual parameters at the same time. (Both are guaranteed to be the same length.) Previously, we used a pattern of: exec_list_iterator 1st_iter = <1st list>.iterator(); foreach_iter(exec_list_iterator, 2nd_iter, <2nd list>) { ... 1st_iter.next(); } This was awkward, since you had to manually iterate through one of the two lists. This patch introduces a foreach_two_lists macro which safely walks through two lists at the same time, so you can simply do: foreach_two_lists(1st_node, <1st list>, 2nd_node, <2nd list>) { ... } v2: Rename macro from foreach_list2 to foreach_two_lists, as suggested by Ian Romanick.

| | | | | | | | | | | | | | | | | | | | | This reduces confusion since gl_shader::Type is sometimes GL_SHADER_PROGRAM_MESA but is more frequently GL_SHADER_{VERTEX,GEOMETRY,FRAGMENT}. It also has the advantage that when switching on gl_shader::Stage, the compiler will alert if one of the possible enum types is unhandled. Finally, many functions in src/glsl (especially those dealing with linking) already use gl_shader_stage to represent pipeline stages; using gl_shader::Stage in those functions avoids the need for a conversion. Note: in the process I changed _mesa_write_shader_to_file() so that if it encounters an unexpected shader stage, it will use a file suffix of "????" rather than "geom".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | This patch creates a new generic is_value() method, which checks if an ir_constant has a particular value. (For vectors, it must have the single value repeated across all components.) It then rewrites the is_zero/is_one/is_negative_one methods to use this generic helper. All three were basically identical except for the value they checked for. The other difference is that is_negative_one rejects boolean types. The new is_value function maintains this behavior, only allowing boolean types when checking for 0 or 1.
