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
2009-06-26glsl: don't unroll loops containing continue/breakBrian Paul
Just search the AST in _slang_can_unroll_for_loop().
2009-06-26Revert "slang: if/else/break & if/else/continue work for unrolled loops"Brian Paul
We should just check if the loop contains a continue/break in the _slang_can_unroll_for_loop() test function... This reverts commit 989856bde47d699d7e18798df4013fbf962e1d4b. Conflicts: src/mesa/shader/slang/slang_codegen.h
2009-06-26glsl: Added gl_shader_state::EmitContReturn fieldBrian Paul
This is the start of a glsl-continue-return feature branch to support a GLSL code generator option for 'continue' and 'return' statements. Some targets don't support CONT or RET statements so we'll need to try to generate code that does not use them...
2009-06-22mesa: rename MAX_VERTEX_ATTRIBS to MAX_VERTEX_GENERIC_ATTRIBSBrian Paul
Be clearer that this is the number of generic vertex program/shader attributes, not counting the legacy attributes (pos, normal, color, etc). (cherry picked from commit 4a95185c9f30c2de7a03bb1a0653f51b53b1111d)

2009-06-08mesa: better error message for invalid texture unit indexBrian Paul
2009-05-08mesa: more complete fix for transform_invarient glitchesKeith Whitwell
Add a new flag mvp_with_dp4 in the context, and use that to switch both ffvertex.c and programopt.c vertex transformation code to either DP4 or MUL/MAD implementations.
2009-04-29mesa: added _mesa_check_soa_dependencies() functionBrian Paul
This function will check an instruction to see if there's data dependencies between the dst and src registers if executed in an SOA manner.
