2009-09-14glsl: added some link debug code (disabled)Brian Paul
2009-09-14glsl: remove extra #version directives from concatenated shader sourcesBrian Paul
When we concatenate shaders to do our form of poor-man linking, if there's multiple #version directives, preprocessing fails. This change disables the extra #version directives by changing the first two chars to //. This should help with some Wine issues such as bug 23946.
2009-08-27mesa: direct program debug output to stderr instead of stdoutmarvin24
2009-08-26glsl: signal that the program needs to be re-translated when samplers changeBrian Paul
2009-08-26glsl: fix bug in sampler array indexingBrian Paul
Need to add the 'offset' parameter when indexing the parameter array. Before, if we were setting arrays of samplers, we were actually only setting the 0th sampler's value. Because of how progs/glsl/samplers.c is constructed, this wasn't showing up as a failure in the samplers_array output.
2009-08-24ARB prog: Set error instead of falling through with incorrect valueBrian Paul
If a fragment program only parameter was queried of a vertex program (e.g., GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB) no error would be set and a random value would be returned. This caused 'glxinfo -l' to show the same values for GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB, GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB as for GL_MAX_PROGRAM_ENV_PARAMETERS_ARB. This is confusing and incorrect. (cherry picked from master, commit 4bccd693a72a0b42dffc849034263a68e779ca91)
2009-08-24glsl: Silence gcc uninitialized variable warning.Vinson Lee
2009-08-13glsl: fix some uninitialized pointersBrian Paul
2009-07-30mesa: move misplaced return statementBrian Paul
Fixes regression from commit 7d93f817c9c5222e2bdbaa9fa9f03fc502bfe878
2009-07-30mesa: add missing return after catching program errorBrian Paul
2009-07-09glsl: do const parameter optimization for array element actual parametersBrian Paul
When a function parameter is const-qualified we can avoid making a copy of the actual parameter (we basically do a search/replace when inlining). This is now done for array element params too, resulting in better code (fewer MOV instructions). We should allow some other types of function arguments here but let's be conservative for the moment.
2009-07-09glsl: fix incorrect indexing for gl_TextureMatrix[i][j]Brian Paul
The two indexes were mixed up when accessing a row of a matrix in an array of matrices.
2009-07-03mesa/shaders: fix gl_NormalMatrix state parametersKeith Whitwell
gl_NormalMatrix is the inverse transpose of the modelview matrix, but as every matrix here needs to be transposed, we end up with {MODELVIEW_MATRIX, INVERSE}.
2009-07-02mesa: s/TRUE/GL_TRUEKeith Whitwell
Fix compile breakage on Linux.
2009-07-02mesa: ensure UsesFogFragCoord value is set for non-glsl shadersKeith Whitwell
With recent changes to support frontfacing in glsl, it is necessary to ensure that the UsesFogFragCoord value is accurate in all shaders. We were previously not setting it for fixed-function and ARB_fs shaders.
2009-06-26glsl: check number of varying variables against the limitBrian Paul
Link fails if too many varying vars. (cherry picked from master, commit cc58fbcf2c5c88f406818db60910f537e03610d6)
2009-06-26glsl: move/simplify error checking for 'return' statementsBrian Paul
2009-06-26glsl: overhaul 'return' statement handlingBrian Paul
A new node type (SLANG_OPER_RETURN_INLINED) is used to denote 'return' statements inside inlined functions which need special handling. All glean glsl1 tests pass for EmitContReturn=FALSE and TRUE.
2009-06-26glsl: predicate assignments according to __returnFlagBrian Paul
Fixes glean "function with early return (3)" case (when EmitContReturn=FALSE).
2009-06-26glsl: added slang_variable::is_global fieldBrian Paul
2009-06-26glsl: silence a problem warningBrian Paul
2009-06-26glsl: code refactoring for return statementsBrian Paul
2009-06-26glsl: fix assorted regressions related to early-return-removalBrian Paul
2009-06-26glsl: comments, field reorderingBrian Paul
2009-06-26glsl: rework loop nesting codeBrian Paul
2009-06-26glsl: remove test for loop unrolling when we hit conditional cont/breakBrian Paul
This is no longer needed since we added the new _slang_loop_contains_continue_or_break() function/test.
2009-06-26glsl: checkpoint: predicate __retVal = expr with __returnFlagBrian Paul
The glean "function with early return (1)" test passes now.
2009-06-26glsl: use new helper functions in _slang_gen_logical_and/or()Brian Paul
2009-06-26glsl: add commentsBrian Paul
2009-06-26glsl: checkpoint: replace 'return' with __returnFlag=true;Brian Paul
Needed for "remove early returns" transformation.
2009-06-26glsl: fix up scoping for parent/children in slang_operation_copy()Brian Paul
This will need more testing, but no regressions seen so far.
2009-06-26glsl: fix uninitialized var in _slang_gen_for_without_continue()Brian Paul
2009-06-26glsl: added slang_operation_free_children()Brian Paul
2009-06-26glsl: added slang_oper_num_children() helperBrian Paul
2009-06-26glsl: check-point: declare _returnFlagBrian Paul
2009-06-26glsl: added slang_operation_insert_child()Brian Paul
2009-06-26glsl: use slang_generate_declaration() to consolidate some codeBrian Paul
2009-06-26glsl: remove obsolete commentBrian Paul
2009-06-26glsl: implement _slang_gen_while_without_continue()Brian Paul
2009-06-26glsl: fix a bug involving 'continue' in 'for' loopsBrian Paul
Need to execute the for loop's increment code before we continue. Add a slang_assemble_ctx::CurLoopOper field to keep track of the containing loop and avoid the "cont if true" path in this situation. Plus, assorted clean-ups.
2009-06-26glsl: added slang_oper_child_const()Brian Paul
2009-06-26glsl: use _slang_loop_contains_continue_or_break() to check for unrollingBrian Paul
The previous test failed for nested loops.
2009-06-26glsl: use new _slang_loop_contains_continue() helper functionBrian Paul
2009-06-26glsl: implement continue->break translation for do-while loopsBrian Paul
2009-06-26glsl: added slang_operation_literal_int/bool() helper functionsBrian Paul
2009-06-26glsl: don't allocate 0-length children array in slang_operation_copy()Brian Paul
2009-06-26glsl: remove debug code, misc clean-upBrian Paul
2009-06-26glsl: implement continue->break transformation for for-loopsBrian Paul
2009-06-26glsl: added slang_operation_add_children() and slang_oper_child() helpersBrian Paul
2009-06-26glsl: added slang_assemble_ctx::EmitContReturn field, initBrian Paul
