2010-09-07glsl: Recognize GLSL ES 1.00 keywords.Kenneth Graunke
2010-09-07glsl: Accept language version 100 and make it the default on ES2.Kenneth Graunke
2010-09-07glsl: Set default language version in mesa_glsl_parse_state constructor.Kenneth Graunke
This should make it easier to change the default version based on the API (say, version 1.00 for OpenGL ES). Also, synchronize the symbol table's version with the parse state's version just before doing AST-to-HIR. This way, it will be set when it matters, but the main initialization code doesn't have to care about the symbol table.
2010-09-07glsl: Change grammar rules for selection statements to match the spec.Kenneth Graunke
Fixes piglit test case loop-06.vert. Unfortunately, causes 1 shift/reduce conflict.
2010-08-30glsl2: Parse #pragma linesIan Romanick
All pragmas are currently ignored. Also, the error messages when a pragma is used incorrectly (i.e., '#pragma debug(on)' inside a function) are crap, but I think this is sufficient for now. Fixes piglit test cases pragma-0[1-8].(vert|frag).
2010-08-26glsl: Use a single shared namespace in the symbol table.Kenneth Graunke
As of 1.20, variable names, function names, and structure type names all share a single namespace, and should conflict with one another in the same scope, or hide each other in nested scopes. However, in 1.10, variables and functions can share the same name in the same scope. Structure types, however, conflict with/hide both. Fixes piglit tests redeclaration-06.vert, redeclaration-11.vert, redeclaration-19.vert, and struct-05.vert.
2010-08-13glsl2: Remove unnecessary use of 'struct' before type namesIan Romanick
In C++ you don't have to say 'struct' or 'class' if the declaration of the type has been seen. Some compilers will complain if you use 'struct' when 'class' should have been used and vice versa. Fixes bugzilla #29539.
2010-08-13glsl2: Avoid token name collisions with names used by Windows header filesIan Romanick
2010-08-13glsl2: Eliminate tokens for square matrix short namesIan Romanick
MAT2 and MAT2X2, for example, are treated identically by the parser. The language version based error checking (becuase mat2x2 is not available in GLSL 1.10) is already done in the lexer.
2010-08-11glsl2: Use bison command line option to set prefixIan Romanick
Bison version 2.3 doesn't seem to support %name-prefix in the source. This should fix bugzilla #29207.
2010-08-11glsl2: Emit error from lexer when illegal reserved word is encounteredIan Romanick
Without this, the parser will generate obtuse, useless error diagnostics when reservered word that are not used by the grammar are encountered in a shader. Fixes bugzilla #29519.
2010-08-10glsl2: Initialize location structure at beginning of parse.Carl Worth
Since we have a custom structure for YYLTYPE locations, we need to use an %initial-action directive to avoid triggering use of uninitialized memory when, for example, printing error messages. Thanks to valgrind for noticing this bug.
2010-08-07glsl2: Add the 1.30 reserved keywords.Kenneth Graunke
2010-08-02glsl2: Fix spelling of "precision" in error output.Eric Anholt
2010-07-28glsl2: Parser support for GL_ARB_fragment_coord_conventionsIan Romanick
2010-07-20glsl2: Remove incorrect assertion in the parser.Kenneth Graunke
This assertion is triggered by method calls (i.e. array.length()), where subexpressions[1] is an ast_function_call expression. Since the assertion itself had a comment saying it could be removed eventually, simply do so. Causes negative glslparser tests array-length-110.frag, array-length-args.frag, and array-length-unsized.frag to pass, but only because the length() method is not supported yet.
2010-07-01glsl2: Append _TOK to some parser tokensIan Romanick
This prevents conflicts with defines elsewhere in Mesa and allows including mtypes.h in the compiler.
2010-06-30glsl2: Use _mesa_glsl_parse_state as the talloc parent, not glsl_shader.Kenneth Graunke
_mesa_glsl_parse_state should be the parent for all temporary allocation done while compiling a shader. glsl_shader should only be used as the parent for the shader's final IR---the _result_ of compilation. Since many IR instructions may be added or discarded during optimization passes, IR should not ever be allocated to glsl_shader directly. Done via sed -i s/talloc_parent(state)/state/g and s/talloc_parent(st)/st/g. This also removes a ton of talloc_parent calls, which may help performance.
2010-06-24glsl2: Move the compiler to the subdirectory it will live in in Mesa.Eric Anholt
