TODO
====
- Look if the =0 variable initializations can be reduced further. (most notably for multi-value variable initialization).
See canSkipInitializationWith0()?
Remove it if there is another normal assignment after the initialization assignment,
that does not use the variable itself somewhere in the value, and the value doesn't contain a functioncall.
Set the "initializer" boolean to true on the first assignment that remains.
- Make some of the target machine config externally configurable (for 1 new target, the existing ones should stay as they are for the time being)
- add paypal donation button as well?

---------
- Sorting module gnomesort_uw could be optimized more, rewrite in asm? Shellshort seems consistently faster even if most of the words are already sorted.
- Add split-word array sorting routines to sorting module?
- add even more general raster irq routines to build some sort of "copper list" , like Oscar64 has?
- pet32 target: make syslib more complete (missing kernal routines)?
- need help with: PET disk routines (OPEN, SETLFS etc are not exposed as kernal calls)
- fix the problems in atari target, and flesh out its libraries.

Optimizations
-------------
- Look if the =0 variable initializations can be reduced further. (most notably for multi-value variable initialization)
- Compare output of some Oscar64 samples to what prog8 does for the equivalent code (see https://github.com/drmortalwombat/OscarTutorials/tree/main and https://github.com/drmortalwombat/oscar64/tree/main/samples)
- Multi-value returns of normal subroutines: use cpu register A or AY for the first one and only start using virtual registers for the rest.
Can FAC then be used for floats as well again? Those are now not supported for multi-value returns.
- Optimize the IfExpression code generation to be more like regular if-else code. (both 6502 and IR) search for "TODO don't store condition as expression"
