symbol types are, by definition, in the .data section, so it is
correct to use SECT_OFF_DATA (objfile) here, not data_sect_index.
If there is no .data section, there should be no N_DATA or N_DATA
| N_EXT symbols.
From Elena Zannoni <ezannoni@redhat.com>
* dbxread.c (process_one_symbol): Only record line 0 if one or
more sline entries have been seen for the function.
From Jim Ingham <jingham@apple.com>:
* dbxread.c (process_one_symbol): Use last_function_start rather
than function_start_offset to find the real beginning of the
current function. The latter is just the text section offset on
some systems, the former is always the real function start.
(fill_symbuf): Support an in-memory buffer for stabs data.
(stabs_seek): New function.
(dbx_psymtab_to_symtab): Relocate the stabs data if necessary.
(read_ofile_symtab): Use stabs_seek.
(elfstab_build_psymtabs): Take an asection* instead of
an offset and size. Relocate the stabs data if necessary.
Save the section* for dbx_psymtab_to_symtab.
* dwarf2read.c: Add section variables for each debug section.
(dwarf2_locate_sections): Fill them in.
(dwarf2_read_section): Take an asection* argument.
Relocate the section contents if necessary.
(dwarf2_build_psymtabs, dwarf2_build_psymtabs_easy): Update callers.
* dwarf2cfi.c (parse_frame_info): Take a section argument and pass
it to dwarf2_read_section.
(dwarf2_build_frame_info): Update callers.

elfstab_build_psymtabs.

* buildsym.h (pop_context): Convert to function, defined in
buildsym.c.

(pop_context): Implement as C function. Add check for stack
underflow.
* dbxread.c (process_one_symbol): Complain and stop processing
that symbol if we are already at the top of the context stack for
a function-end N_FUN (this would imply an umatched RBRAC). Ditto
when processing N_RBRAC.
texthigh and textlow to reader-specific structs caused
objfile_relocate to miss them. This is fixable, but the work that
the change was supposed to prepare GDB for never got done anyway.
* symtab.h (find_stab_function_addr): Kill extern.
* minsyms.c (find_stab_function_addr): Remove from here...
* dbxread.c: ... to here, and mark it static.
2002-02-21 Fred Fish <fnf@redhat.com>
* dbxread.c (process_one_symbol): When finding an N_FUN symbol
that marks the end of the range of a function, enter a line number
entry that has a line number of zero and a PC offset that matches
the end of the function. This starts a range of PC's for which no
line number information is known.
* symtab.c (find_pc_sect_line): If our best fit is in a range of
PC's for which no line number info is found (line number is zero)
then we didn't find any valid line information.
* symtab.h: Document use of zero line number entry.
* dbxread.c (set_namestring): New function, replacing the
SET_NAMESTRING macro.

cp-abi.h.
