* glsl: Add support for default layout qualifiers for uniforms.Eric Anholt2012-07-311-38/+20
| | | | | | | | | | | I ended up having to add rallocing of the ast_type_qualifier in order to avoid pulling in ast.h for glsl_parser_extras.h, because I wanted to track an ast_type_qualifier in the state.

* glsl: Refactor #version validation to be more future-proof.Kenneth Graunke2012-07-311-8/+15
| | | | | | | | | | | | | | | | | The previous implementation required a flag in _mesa_glsl_parse_state and line of code to initialize it for every version of the shading language we intend to support. As we look to add 150, 330, 400, 410, 420, and beyond, this gets rather unwieldy. This patch retains the switch statement (to reject, say, #version 111), but removes all the bits. Code to check for ctx->API == API_OPENGL_CORE could easily be added to the 110 and 120 cases to reject those. v2: Use _mesa_is_desktop_gl to preserve the existing behavior in the presence of the new API_OPENGL_CORE enumeration.

* glsl: Fix #pragma invariant(all) language version check.Kenneth Graunke2012-07-311-1/+1
| | | | | | | | | | | | | It was using state->Const.GLSL_100ES, which is set if the driver supports ARB_ES2_compatibility or we're in ES2 mode. Instead, it should use state->language_version, as that represents the actual GLSL version of the shader being compiled. Since the correct logic is < 120 && !100, just make it == 110.

* glsl: add support for ARB_blend_func_extended (v3)Dave Airlie2012-04-131-0/+20
| | | | | | | | | | | | | | | | | | | This adds index support to the GLSL compiler. I'm not 100% sure of my approach here, esp without how output ordering happens wrt location, index pairs, in the "mark" function. Since current hw doesn't ever have a location > 0 with an index > 0, we don't have to work out if the output ordering the hw requires is location, index, location, index or location, location, index, index. But we have no hw to know, so punt on it for now. v2: index requires layout - catch and error setup explicit index properly. v3: drop idx_offset stuff, assume index follow location Signed-off-by: Dave Airlie <[email protected]>

| | | | | | | | | The samplerBuffer type will be undefined in !glsl 1.40, and the keyword is marked as reserved.

* glsl: Fix crashes caused by Bison error messages involving "'%'".Kenneth Graunke2011-12-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Invalid shaders containing the character % at an unexpected location would cause Bison to call yyerror with a message of: syntax error, unexpected '%' Bison expects yyerror() to take a string, while _mesa_glsl_error() is a printf-style function. This hit the classic printf string escape issue: _mesa_glsl_error(loc, state, "unexpected '%'"); // invalid! _mesa_glsl_error(loc, state, "%s", "unexpected '%'"); // correct. This caused assertion failures after ralloc_asprintf_append called vsnprintf to determine the length of the text that would be printed: vsnprintf would see the invalid format and return -1, an invalid length. The solution is to define a proper yyerror() wrapper function that calls _mesa_glsl_error with the "%s". Since we compile with -p "_mesa_glsl", yyerror is defined as: #define yyerror _mesa_glsl_error So we have to #undef yyerror in order to be able to declare it.

* glsl: Reference data structure ctors in grammarDan McCabe2011-11-071-16/+39
| | | | | | | | | | | | | | | | | We now tie the grammar to the ctors of the ASTs they reference. This requires that we actually have definitions of the ctors. In addition, we also need to define "print" and "hir" methods for the AST classes. The Print methods are pretty simple to flesh out. However, at this stage of the development, we simply stub out the "hir" methods and flesh them out later. Also, since actual class instances get returned by the productions in the grammar, we also need to designate the type of the productions that reference those instances.

* glsl: Add productions to GLSL grammar for switch statementDan McCabe2011-11-071-3/+61
| | | | | | | | | | | | | The grammar is modified to support switch statements. Rather than follow the grammar in the appendix, which allows case labels to be placed ANYWHERE as a regular statement, we follow the development of the grammar as described in the body of the GLSL spec. In this variation, the switch statement has a body which consists of a list of case statements. A case statement is preceded by a list of case labels and ends with a list of statements.
