TODO
|
|
====
|
|
|
|
- possible idea: option to mark vardecls 'shared' to indicate they should not be optimized away because they're shared with assembly code?
|
|
However: who even needs variables declared in prog8 code that are only used by assembly???
|
|
- github issue: make strings no longer immutable? Deduplication selectable via command line switch?
|
|
|
|
- test all examples before release of the new version
|
|
|
|
- simplify cx16.joystick_get2() once this cx16 rom issue is resolved: https://github.com/commanderx16/x16-rom/issues/203
|
|
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
|
|
- get rid of all other TODO's in the code ;-)

Low prio
|
|
^^^^^^^^
|
|
- see if we can remove more ".typeOrElse(DataType.UNDEFINED)"
|
|
- optimize several inner loops in gfx2 even further?
|
|
- add modes 2 and 3 to gfx2 (lowres 4 color and 16 color)?
|
|
- add a flood fill routine to gfx2?
|
|
- add a f_seek() routine for the Cx16 that uses its seek dos api?
|
|
- refactor the asmgen into own submodule
|
|
- refactor the compiler optimizers into own submodule
|
|
- add a compiler option to not remove unused subroutines. this allows for building library programs. But this won't work with 64tass's .proc ...
|
|
- make it possible to use cpu opcodes such as 'nop' as variable names by prefixing all asm vars with something such as ``v_``
|
|
|
|
More optimizations
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
Add more compiler optimizations to the existing ones.
|
|
|
|
- find a way to optimize if-statement codegen so that "if var & %10000" doesn't use stack & subroutine call, but also that the simple case "if X {...}" remains fast
|
|
- 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
|
|
- further optimize assignment codegeneration, such as the following:
|
|
- rewrite expression code generator to not use eval stack but a fixed number of predetermined value 'variables' (1 per nesting level?)
|
|
- binexpr splitting (beware self-referencing expressions and asm code ballooning though)
|
|
- more optimizations on the language AST level
|
|
- more optimizations on the final assembly source level
|
|
|
|
|
|
Misc

Several ideas were discussed on my reddit post
