501ee87180 Lots of changes to prog_print.c code. 
Mainly, allow printing programs in either ARB, NV or "debug" formats.

bd9615bbc5 Check for constant-valued while/do loop conditions. 
Allows us to:
1. avoid generating constant-valued BRK test for while(1)..
2. discard entire loop for while(0).
3. detection infinite loops at compile-time.

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).

d434019633 additional comments for BranchTarget 2007-02-05 18:04:35 -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.
 2007-02-05 18:01:02 -07:00
Brian
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.
