I'd guess that the author of the code generator simply coped with the
easier, more common, case and put the assert() in to catch the uncommon,
not implemented yet, case rather than stumbling blindly on making
debugging more difficult.
In other words, the code generator needs improving to cope with a jump
to an address that is too far away for a PC-relative jump.
