 Improve register load order in subroutine call args assignments:
 in certain situations, the "wrong" order of evaluation of function call arguments is done which results
 in overwriting registers that already got their value, which requires a lot of stack juggling (especially on plain 6502 cpu!)
@@ -11,7 +13,6 @@ Future Things and Ideas
 ^^^^^^^^^^^^^^^^^^^^^^^
 - Improve the SublimeText syntax file for prog8, you can also install this for 'bat': https://github.com/sharkdp/bat?tab=readme-ov-file#adding-new-syntaxes--language-definitions
 - Can we support signed % (remainder) somehow?
-- Don't add "random" rts to %asm blocks but instead give a warning about it? (but this breaks existing behavior that others already depend on... command line switch? block directive?)
 - IR: implement missing operators in AssignmentGen  (array shifts etc)
 - instead of copy-pasting inline asmsubs, make them into a 64tass macro and use that instead.
   that will allow them to be reused from custom user written assembly code as well.
