* Checkpoint: implementing true CAL/RET instructions for subroutine calls.Brian2007-03-264-13/+92
| | | | | | 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.

* r300: Remove a warning when vertex programs produce an unused outputNicolai Haehnle2007-03-261-3/+2
| | | | | | | | | | | As far as we know, the hardware prefers outputs packed tightly together with no holes caused by outputs that are not even read by the fragment program. Therefore, we slightly rewrite vertex programs in this case. It would be interesting to test this interaction between vertex programs and fragment programs further, because some of that rewrite may be unnecessary. However, play it safe for now and don't change the current behaviour.

| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.
