Task list for completing PIRC

[kjs]

Task list can be found in compilers/pirc/TODO, and includes:

1. Emit the actual bytecodes into a PackFile/codesegment. This is done.

2. Create a PMC constant for strings, numbers, keys and

subroutines.

Strings, numbers and subs are stored. Keys still todo.

3. Complete PASM output, so it can actually be parsed and run. TODO

4. Handle :multi flag properly. TODO

5. Handle nested macro expansions. TODO

6. Fix all memory leaks. this should be trivial, given PIR's built-in

allocated-memory-pointer-registering infrastructure. In some places this is not used yet, and in others, it's not necessary to use it (but in those mem_sys_free() must be called explicitly).

TODO

7. Figure out how :named argument passing works in bytecode. TODO

8. Finish the parrot calling conventions ops in the back-end

(var.args must be fixed).

DONE.

This is a tracking ticket.
