OBJFILE is where the symbols are to be read from.
ADDRS is the list of section load addresses. If the user has given
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
breakpoint reset should be deferred. */
