TODO's for new Constant Solution
|
|
||||||
+ Live range overlap analysis of register combinations inside methods must also look at registers alive at all calls.
|
|
||||||
+ Examine why temp-vars are used in flipper.
|
|
||||||
+ Examine why flipper is plotted in a wrong position on the screen.
|
|
||||||
+ Implement constants into the symbol table and support them in code.
|
|
||||||
- Implement new constant consolidation steps.
|
|
||||||
- Reintroduce constant addition optimization
|
|
||||||
+ Add asmName for ConstantVar to remove subscripts
|
|
||||||
+ Inline constants for "single" versions of vars - such as .const i#0 = 0
|
|
||||||
+ Look at optimizing liverange.kc's ASM further - atm. there are to many copy-operations into unnecesary registers.
|
|
||||||
+ In summin.asm the result of the 2nd sum() is clobbered twice during call to sum(). jsr sum, txa, lda #$d, ldx #$9, jsr sum
|
|
||||||
+ Fix by introducing "effective alive vars" which includes alive vars at all calls to containing methods and using that during clobber check.
|
|
||||||
+ In loopnest.asm x&y are used in both loops - the outer x&y are clobbered by the inner loop.
|
|
||||||
+ In voronoi.asm in render() x is clobbered during call to findcol().

- Move the main code into a main() function, and disallow code outside functions. The main function per default has no parameters and exits with RTS.
