* Fix issues related to the 'continue' statement.Brian2007-03-233-52/+126
| | | | | | | | 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.

* Add the ability to generate programs that doesn't use condition codes.Brian2007-03-238-51/+176
| | | | | | | ctx->Shader.EmitCondCodes determines if we use condition codes. If not, IF statement uses first operand's X component as the condition. Added OPCODE_BRK0, OPCODE_BRK1, OPCODE_CONT0, OPCODE_CONT1 to handle the common cases of conditional break/continue.

* Overhaul emit_compare() function.Brian2007-03-223-36/+143
| | | | | | | | 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.
* First pass at implementing structure compares.Brian2007-03-221-9/+28
| | | | | Need to improve this. There may be holes in a structure so we can't just blindly compare the full 4-float registers.

| * r300: Remove the program-global const_sin indexNicolai Haehnle2007-03-212-31/+23
| | | | | | | | | | | | | | The index is no longer necessary to share constants between multiple SIN/COS/SCS instructions inside a single fragment program, and storing a tiny implementation detail like this in the fragment_program structure itself was just nasty.

| * r300: Cleanup fragment program constant allocation, share constantsNicolai Haehnle2007-03-192-73/+61
| | | | | | | | | | | | | | | | | | The constant/parameter allocation was significantly simplified, removing one unnecessary copy operation of parameters. The dirty state tracking is unchanged and far from optimal, since all state is always re-fetched. Constants and parameters are now emitted only once, which significantly reduces the resource pressure on larger programs.
| * r300: Fix special case (tmp.x <= 0) in fragment program LIT instructionNicolai Haehnle2007-03-191-2/+2
| | | | | | | | Also, fix a typo in a related comment.
| * r300: Clear fragment program instruction slots on first useNicolai Haehnle2007-03-191-0/+2
| | | | | | | | | | | | | | | | Make sure that instruction slots are fully initialized with NOPs during find_and_prepare_slot(). This fixes a bug when a fragment program was translated more than once (e.g. due to a second call to glProgramStringARB). This partially fixes glean/fragProg1.

| * r300: Fix WRITEMASK handling when writing to result.depthNicolai Haehnle2007-03-191-3/+8
| | | | | | | | | | | | | | | | | | This is a necessary change to emit the right instructions when writing to result.depth. However, even with this test, Z-write doesn't work properly, and I don't fully understand why. In addition to this, we'll at least have to disable early-Z, but even that doesn't seem to be enough.
| * r300: Streamlined fragment program LIT implementationNicolai Haehnle2007-03-191-62/+101
| | | | | | | | | | | | | | | | Fix a bug in the LIT implementation (clamp exponent to 128, not 0.5) and change the implementation around. In theory, the new implementation needs as little as 5 instruction slots. Unfortunately, the dependency analysis in find_and_replace_slot is not strong enough to look at individual components of a register yet.
| * r300: Fix fragment program reorderingNicolai Haehnle2007-03-192-5/+37
| | | | | | | | | | Do not move an instruction that writes to a temp forward past an instruction that reads the same temporary.
