- add sound to the cx16 tehtriz
2021-02-20 01:27:57 +00:00
2021-02-16 22:58:31 +00:00
- hoist all variable declarations up to the subroutine scope *before* even the constant folding takes place (to avoid undefined symbol errors when referring to a variable from another nested scope in the subroutine)
2021-02-07 18:08:47 +00:00
- optimize swap of two memread values with index, using the same pointer expression/variable, like swap(@(ptr+1), @(ptr+2))
2021-02-06 00:15:47 +00:00
- optimize several inner loops in gfx2 (highres 4 color mode)
2021-01-24 13:03:01 +00:00
- use the 65c02 bit clear/set/test instructions for single-bit operations
2021-02-07 18:08:47 +00:00
- try to fix the bresenham line routines in graphics and gfx2 (sometimes they're a pixel 'off')
2021-02-20 15:58:24 +00:00
- add modes 2 and 3 to gfx2 (lowres 4 color and 16 color)
2021-02-07 18:08:47 +00:00
- add a flood fill routine to gfx2?
2021-01-16 17:09:47 +00:00
- add a f_seek() routine for the Cx16 that uses its seek dos api?
2021-02-20 16:33:45 +00:00
- refactor the asmgen into their own submodule?
- refactor the compiler optimizers into their own submodule?
2021-01-07 00:25:50 +00:00
- optimizer: detect variables that are written but never read - mark those as unused too and remove them, such as uword unused = memory("unused222", 20) - also remove the memory slab allocation
2021-01-19 23:28:54 +00:00
- add a compiler option to not remove unused subroutines. this allows for building library programs
2021-02-15 03:41:33 +00:00
- make it possible to use cpu opcodes such as 'nop' as variable names by prefixing all asm vars with something such as 'v_'
2020-08-18 12:47:52 +00:00
- option to load the built-in library files from a directory instead of the embedded ones (for easier library development/debugging)
2021-02-15 03:41:33 +00:00
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
2020-11-10 21:44:48 +00:00
- some support for recursive subroutines?
- via %option recursive?: allocate all params and local vars on estack, don't allow nested subroutines, can begin by first not allowing any local variables just fixing the parameters
- Or via a special recursive call operation that copies the current values of all local vars (including arguments) to the stack, replaces the arguments, jsr subroutine, and after returning copy the stack back to the local variables
2020-10-22 21:41:16 +00:00
- get rid of all other TODO's in the code ;-)

More optimizations
^^^^^^^^^^^^^^^^^^
Add more compiler optimizations to the existing ones.
2020-10-02 20:37:52 +00:00
- further optimize assignment codegeneration, such as the following:
2021-02-15 03:41:33 +00:00
- rewrite expression code generator to not use eval stack but a fixed number of predetermined value 'variables' (1 per nesting level?)
2020-10-02 20:37:52 +00:00
- binexpr splitting (beware self-referencing expressions and asm code ballooning though)
2020-03-24 21:37:42 +00:00
- more optimizations on the language AST level
- more optimizations on the final assembly source level
