The output of this issue is more issues on the roadmap.

Figure out how debugging will be implemented. Loose notes:

  • A debugger can provide breakpoints by inserting a TRAP behind or in front of a target instruction
  • A debugger can provide a watchpoint-on-access by inspecting incoming instructions for matching operands
  • The debugger is an NCURSES interface that extends the program loader.

Unclear how this behaves when the user attempts to interact with a program as compiled code.

  • debug symbols need to be implemented (maybe as a trap that expands/contracts a moving stack of function names?
  • A debugger can provide a watchpoint-on-access and watchpoint-on-write by intercepting access to/from the symbol map
  • A debugger can provide breakpoints into compiled code if debug symbols are added to the code.... probably lol.
