PBC Object Files

[Michael Collins]

Is there currently a specification for a pbc "object file" for linking and dynamic
loading?

By "object file" I guess mean a file that contains compiled instructions plus
a section with a table that maps subroutine/constant labels to their corresponding
byte offsets within the file.

If no, it might be useful.

No, not yet. Packfile loading and some parrot guts still need more
cleanup for getting multiple bytecode sections running.

Yep. The basic functionality is already there. But some internal
structures like constant and fixup table need some rework to do it
right. And of course we need some opcodes to load another PBC file.

And needed.
