dbgfile misses linker generated symbols

[pm100]

The --dbgfile output generates a lot of symbol info but it misses the ones generated by the linker (__MAIN_SIZE__, __STACK_SIZE___,....). The imports are listed but not the definitions, and hence not the values.

This info is in the map file and in the VICE label file but its a pain to have to generate and parse two files.

I have code that adds all exports that have E->Obj == NULL (which identifies linker generated symbols) as additional 'sym' records. But

• they have 'fake' ids, I simply start numbering form the last real sym record
• they dont have parent or scope since these are derived from the owner , and so break the pattern of the other sym records
• they dont have def lines, since they dont really exist

These oddities might disturb other code that reads the dbgfile

An alternative would be to add a new dbgfile record , say 'lsym' for 'linker symbol'
