TODO
|
|
====
|
|
|
|
For next release
|
|
^^^^^^^^^^^^^^^^
|
|
- rename libdirs option to srcdirs?
|
|
- can we derive module.name from module.source (taking just the filename base)?
|
|
- can Position.file be a Path- making the source variable for nodes unnecessary?
|
|
|
|
|
|
- refactor code to improve testability and other things, see [CompilerDevelopment](CompilerDevelopment.md)
|
|
- simplify cx16.joystick_get2() once this cx16 rom issue is resolved: https://github.com/commanderx16/x16-rom/issues/203
|
|
(I hope this will still be included into the final v39 roms release for the cx16)
|
|
|
|
|
|
Future
|
|
^^^^^^
|
|
- get rid of all other TODO's in the code ;-)
|
|
- see if we can remove more ".typeOrElse(DataType.UNDEFINED)"
|
|
- should we introduce more optionals to get rid of more null pointers?
|
|
- c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
|
|
- 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 diskio.f_seek() routine for the Cx16 that uses its seek dos api?
|
|
- make it possible for diskio to read and write from more than one file at the same time (= use multiple io channels)?
|
|
- refactor the asmgen into own project submodule
|
|
- refactor the compiler optimizers into own project submodule
|
|
- make it possible to use cpu opcodes such as 'nop' as variable names by prefixing all asm vars with something such as ``v_``
|
|
- [problematic due to 64tass:] add a compiler option to not remove unused subroutines. this allows for building library programs. But this won't work with 64tass's .proc ...
|
|
Perhaps replace all uses of .proc/.pend by .block/.bend will fix that?
|
|
(but we lose the optimizing aspect of the assembler where it strips out unused code.
|
|
There's not really a dynamic switch possible as all assembly lib code is static and uses one or the other)
|
|
- introduce byte-index operator to avoid index multiplications in loops over arrays?
|
|

More code optimizations
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
- 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
|
|
- detect proper variables that are written but never read - mark those as unused too and remove them, such as ``uword unused = memory("unused222", 20)`` - also remove this memory slab allocation
|
|
- rewrite expression tree evaluation such that it doesn't use an eval stack but flatten the tree into linear code that uses a fixed number of predetermined value 'variables'
|
|
- this removes the need for the BinExprSplitter (which is problematic now)
