K65 To Do

Here is my current list of things still to be done in K65 compiler.

• Simple:
  • signal errors on undefined character in string
  • #if's within data
  • #if's within code
  • support for binary numbers
  • report error when section names are reused (e.g. in "inline" section)
  • correct support of <flag>+? and <flag>-? branch operators
  • >={...}>= loops and similar
  • support for negative eval results
  • extend binary operations in eval
  • change ^ operator to bitwise xor in eval
  • 256-byte data section should work with nocross
  • add fixed address option for sections
  • add option to place sections in multiple banks
  • fix lexer hanging on invalid input

• Medium:
  • support for custom palettes
  • mark section as referenced if ANY of its labels are referenced
  • array support
  • option to force full addressing with zeropage addresses
  • include raw binary data from file
  • extend computation on labels (compute "Label1 - Label2 + Offset" )
  • switch to external image loader library (OpenIL?)

• Hard/large:
  • macros
  • pure assembly sections
  • alternate bankswitching schemes
  • alternate platforms
  • per-instruction bank bits
  • linker refactoring
  • generalized linker
  • bank blocks jumping
  • bank checking when getting addresses
  • option to override ORG and RORG execution address
  • "lazy" code sections
  • target files and names (.bin/.lst/.sym) in config file
  • make LST files compatible with DASM/Stella
  • language reference document
