4aa487e796 Use IR_LOOP to represent do-while and for-loops. 
Also, start moving high vs. low-level instruction selection into slang_emit.c

1f99a7514e BRK and CONT work the same 2007-02-06 22:34:09 -07:00
Brian
f22ed0986a Implement CONT, improve BRK. 
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).

2043364516 redo IR_IF node, removing IR_ELSE, IR_ENDIF 2007-02-06 20:45:43 -07:00
Brian
2755c798f3 BRK instruction's BranchTarget field now used for efficiently breaking out 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.

8608079647 Use IR node's BranchNode field for IF/ELSE/ENDIF instructions. 
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.

cf92c72797 Initial implementation of high-level flow-control instructions. 
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.

5db088d70f indentation for program instructions (if/else, loops) 2007-02-05 14:58:15 -07:00
Brian
01001d80e2 Initial support of loop and subroutine instructions. 
New high-level flow-control instructions, both at IR level and GPU instructions
for looping and subroutines.

dd34fe8679 Merge SWvertex texcoord and varying fields into attrib[] array field. 
Fragment texcoords and varying code is now unified in the point/line/triangle
rasterization code.  In the future, merge color, fog, etc. attribs.

93b975a1d9 Add literal_size field to slang_operation. 
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))"

68fc4ff1d7 Add _NEW_PROGRAM flag to _MESA_NEW_NEED_EYE_COORDS. 
This fixes a segfault in the texgen code that can occur after we've
disabled a vertex program.
