|
* 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.

|
* 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.
* consolidate some codeBrian2007-03-231-7/+2
|
* Add the ability to generate programs that doesn't use condition codes.Brian2007-03-236-49/+168
| | | | | | | 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.

| | | | | | | | swizzleOut==NULL. There are times when we don't want to allow swizzling when searching for or adding vector constants. Passing NULL for swizzleOut disables swizzling. This fixes a constant/swizzle bug in link_uniform_vars().
