2008-11-19mesa: rework GLSL array code generationBrian Paul
We now express arrays in terms of indirect addressing. For example: dst = a[i]; becomes: MOV dst, TEMP[1 + TEMP[2].y]; At instruction-emit time indirect addressing is converted into ARL/ ADDR-relative form: ARL ADDR.x, TEMP[2].y; MOV dst, TEMP[1 + ADDR.x]; This fixes a number of array-related issues. Arrays of arrays and complex array/struct nesting works now. There may be some regressions, but more work is coming.
2008-11-13mesa: no longer need Writemask field in GLSL IR nodesBrian Paul
The Swizzle and Size fields carry all the info we need now.
2008-11-07mesa: add GLSL support for DP2, NRM3, NRM4 instructions (not actually ↵Brian Paul
emitted yet though)
2008-08-16mesa: import latest GLSL code from gallium-0.1 branchBrian Paul
2008-07-29mesa: rework array/struct addressing code.Brian Paul
The slang_ir_storage type now has a pointer to parent storage to represent storage of an array element within an array, or a field within a struct. This fixes some problems related to addressing of fields/elements in non- trivial cases. More work to follow.
2008-06-12glsl: implement variable array indexesZack Rusin
2007-07-26Fix function call bug 11731. Also, fix up IR_CALL/IR_FUNC confusion.Brian
2007-03-28remove IR_BREAK_IF_FALSEBrian
2007-03-28Get rid of IR_CONT_IF_FALSEBrian
2007-03-26Checkpoint: implementing true CAL/RET instructions for subroutine calls.Brian
Also, found/fixed a code generation regression: the emit_swizzle() function was always returning NULL. This caused emit_move() to miss its chance at peephole optimization.
2007-03-26Get rid of IR_JUMP and related code.Brian
2007-03-24Properly free the slang_ir_node->Store data (use ref counting).Brian
2007-03-24move some code into new slang_ir.c fileBrian
2007-03-23Fix issues related to the 'continue' statement.Brian
IR_LOOP now has two children: the body code, and the tail code. Tail code is the "i++" part of a for-loop, or the expression at the end of a "do {} while(expr);" loop. "continue" translates into: "execute tail code; CONT;" Also, the test for infinite do/while loops was incorrect.
2007-03-22Overhaul emit_compare() function.Brian
Previously, comparing vec2, vec3, vec4 was broken. Added IR_EQUAL, IR_NOTEQUAL nodes/operators to compute boolean equality/inequality vs. IR_SEQUAL/IR_SNEQUAL which work component-wise. Use IR_EQUAL/IR_NOTEQUAL for the == and != operators. To compute vec4 equality, use SNE, DP4, SEQ instruction sequence.
2007-03-21Support for user-defined structures.Brian
struct == and != operators not finished yet. Struct assignment works though.
2007-03-08Added IR_SLE and IR_SLT for <= and < operations.Brian
Using IR_SGE and IR_SGT with transposed args doesn't work since the __asm calls don't do argument matching by name, but by position. This fixes the broken lessThan() and lessThanEqual() functions.
2007-03-08IR_CJUMP0/1 no longer used/neededBrian
2007-02-23Replace slang_ir_node::Target w/ Field. Remove Comment field. Clean-up.Brian
2007-02-23Re-implement branching with slang_labels.Brian
This eliminates the NOP instructions that had been used as placeholders for branch targets. Also, fix "return" statement bug.
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
2007-02-06replace IR_BEGIN_LOOP/IR_END_LOOP with IR_LOOPBrian
2007-02-06redo IR_IF node, removing IR_ELSE, IR_ENDIFBrian
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.
2007-02-05Initial support of loop and subroutine instructions.Brian
New high-level flow-control instructions, both at IR level and GPU instructions for looping and subroutines.
2007-01-31Overhaul handling of writemasks/swizzling. This fixes two problem cases:Brian
vec2 v; v.x = v.y = 1.0; // chained assignment vec4 v; v.zx = vec2(a,b); // swizzled writemask
2007-01-31New asm instruction and IR_CLAMP node type to allow clamping to [0,1] with ↵Brian
instruction saturate-write option. Not finished yet.
2007-01-28noise functionsBrian
2007-01-28implement mix() with LRP instructionBrian
2007-01-27Clean-up of var/temp allocation function parameters.Brian
2007-01-20Initial implementation of OPCODE_IF/ELSE/ENDIF instructions.Brian
2007-01-19Implement do/while loops. Replace IR_CJUMP with IR_CJUMP0 and IR_CJUMP1 soBrian
we can either jump on zero, or non-zero predicate.
2007-01-19Implement fragment discard/kill.Brian
2007-01-18Reimplement code for swizzling so that expressions like (p+q).x for vectors ↵Brian
p and q works correctly.
2007-01-17added IR_F_TO_I, update commentsBrian
2007-01-15Redo the way array indexes are handled. Resolve storage location at code ↵Brian
emit time, not codegen time.
2007-01-13Rework code related to temp register allocation, both for user variablesBrian
and expression temporarires. Much better register utilization now. Lots of other fixes. The OpenGL GLSL "orange book" brick shader demo works now.
2007-01-09Implement shadow samplers and dFdx(), dFdy() code generation.Brian
2007-01-08Implement projective texture sampling, 3D textures. Disable some debug output.Brian
2007-01-05Checkpoint glsl compiler work: sampler uniforms now implemented, linked ↵Brian
properly.
2007-01-04initial code to get texture sampling limping alongBrian
2006-12-22fix typosBrian
2006-12-21added IR_NEG for negationBrian
2006-12-20New IR_COND node for evaluating conditional expressions (for if/while/for).Brian

2006-12-13Checkpoint new GLSL compiler back-end to produce fp/vp-style assembly ↵Brian
instructions.
