Leo / Dan --
Have we allocated PASM or IMC directives to replace the setline, setfile, and setpackage ops?
* .file <name> * .line [<filename>] <line> * .package <name>
Should we have an indicator of the name of a sub, too?
We don't need .file/.line, imcc knows these, and passes the information in the PBC metadata already to jit_debug. The parrot debugger still needs work.
For HL file/line information I'd rather use (the already in perl6/P6C implemented) comment syntax, like:
#line 13 "mops.p6"
$ imcc -d -o p.pbc primes.pasm
$ pdump -t p.pbc
...
BYTECODE_DB => [ # offs 0xa0(160) = op_count 40, itype 0, id 0, size 32, ...

In the last bytes you can decipher the filename.
