2007-02-17s/PROG_PRINT_ARB/PROG_PRINT_DEBUG/Brian
2007-02-17Lots of changes to prog_print.c code.Brian
Mainly, allow printing programs in either ARB, NV or "debug" formats.

2007-02-09re-enable free'ing of IR treesBrian
2007-02-09always init param vars to silence valgrind warningsBrian
2007-02-09optimize per-pixel fog programRoland Scheidegger
use the same internal state as for vertex fog. From the old implemenentation, this changes a SUB+MUL into a MAD for linear fog, and saves a MUL for EXP/EXP2, plus saves a (constant) parameter. While here, fix the broken (forgotten) swizzling. (untested)
2007-02-08do full swizzled matching in _mesa_lookup_parameter_constant()Brian
2007-02-08Check for constant-valued while/do loop conditions.Brian
Allows us to: 1. avoid generating constant-valued BRK test for while(1).. 2. discard entire loop for while(0). 3. detection infinite loops at compile-time.
2007-02-08optimize conditional breaks/continuesBrian
2007-02-09optimize generated vertex programs a bitRoland Scheidegger
Use new internal state to avoid per-vertex normalization of static spot direction vector. Use internal state for simpler per-vertex fog computations (MAD instead of SUB/MUL for linear fog, EX2 instead of POW for EXP/EXP2 fog). Simplify point size calc (2 MADs instead of MOV, MUL, MUL, DP3), and while there fix it up (RSQ instead of RCP). All untested...
2007-02-08cont at top of loop, little clean-upsBrian
2007-02-08remove some cruftBrian
2007-02-08fix broken BRA for return stmtsBrian
2007-02-08change BranchTarget to GLintBrian
2007-02-08Use conditional break in for/do/while loops.Brian
2007-02-07remove old loop break/cont stuffBrian

2007-02-07Remove old functions for generating BRA-based looping.Brian
2007-02-07Use IR_LOOP to represent do-while and for-loops.Brian
Also, start moving high vs. low-level instruction selection into slang_emit.c
2007-02-06Implement CONT, improve BRK.Brian
IR_LOOP's BranchNode ptr is the head of a linked list of CONT and BRK nodes. After emitting loop, walk over the linked list, filling in the CONT/BRK instruction's BranchTarget field (location of the ENDLOOP instruction, or one past).
2007-02-06replace IR_BEGIN_LOOP/IR_END_LOOP with IR_LOOPBrian
2007-02-06new_node[0123]() functionsBrian
2007-02-06redo IR_IF node, removing IR_ELSE, IR_ENDIFBrian
2007-02-05additional comments for BranchTargetBrian
2007-02-05BRK instruction's BranchTarget field now used for efficiently breaking out ↵Brian
of loops. BRK's BranchTarget field actually points to the top of the loop, not the bottom, since we don't know the later's location yet. In the interpreter, basically do an indirect jump to update the PC.
2007-02-05Use IR node's BranchNode field for IF/ELSE/ENDIF instructions.Brian
This allows us to back-patch the IF/ELSE instruction's BranchTarget field to point to the location of the ELSE/ENDIF instructions. No longer have to search for ELSE/ENDIF in the interpreter. Also makes it trivial to translate IF/ELSE instructions into conditional/unconditional BRA instructions.
2007-02-05minor formatting changesBrian
2007-02-05set UseHighLevelInstructions = false for nowBrian
2007-02-05Initial implementation of high-level flow-control instructions.Brian
IF/ELSE/ENDIF and BEGIN_LOOP/END_LOOP/BREAK instructions seem to work. Disabled by default though until better tested. Implemented IR_NOT, but needs optimization.
2007-02-05indentation for program instructions (if/else, loops)Brian
2007-02-05Initial support of loop and subroutine instructions.Brian
New high-level flow-control instructions, both at IR level and GPU instructions for looping and subroutines.
2007-02-03Add literal_size field to slang_operation.Brian
Used to track the number of components in a float/int/bool literal. Helps with some typechecking things. Fixes problems with calls such as "distance(v2, vec2(1.0, 2.0))"
2007-02-03minor tweaks to distance() funcsBrian
