-/* OK, when we call objfile_relocate, we need to relocate breakpoints
- too. breakpoint_re_set is not a good choice--for example, if
- addr_string contains just a line number without a file name the
- breakpoint might get set in a different file. In general, there is
- no need to go all the way back to the user's string (though this might
- work if some effort were made to canonicalize it), since symtabs and
- everything except addresses are still valid.
-
- Probably the best way to solve this is to have each breakpoint save
- the objfile and the section number that was used to set it (if set
- by "*addr", probably it is best to use find_pc_line to get a symtab
- and use the objfile and block_line_section for that symtab). Then
- objfile_relocate can call fixup_breakpoints with the objfile and
- the new_offsets, and it can relocate only the appropriate breakpoints. */
