into an offset from the section VMA's as it appears in the object
file, and then call the file's sym_offsets function to convert this
into a format-specific offset table --- a `struct section_offsets'.
- If ADDRS is non-zero, OFFSETS must be zero.
-
- OFFSETS is a table of section offsets already in the right
- format-specific representation. NUM_OFFSETS is the number of
- elements present in OFFSETS->offsets. If OFFSETS is non-zero, we
- assume this is the proper table the call to sym_offsets described
- above would produce. Instead of calling sym_offsets, we just dump
- it right into objfile->section_offsets. (When we're re-reading
- symbols from an objfile, we don't have the original load address
- list any more; all we have is the section offset table.) If
- OFFSETS is non-zero, ADDRS must be zero.
ADD_FLAGS encodes verbosity level, whether this is main symbol or
an extra symbol file such as dynamically loaded code, and wether
