single frame backtracing within the library only. Only works when
using the HPUX 9 dynamic linker. More functionality to be added
soon.
* somsolib.c, somsolib.h: New files.
* Makefile.in (HFILES_NO_SRCDIR): Add somsolib.h
(ALLDEPFILES): Add somsolib.c.
(somsolib.o): Add some dependencies.
* mpw-make.in (HFILES_NO_SRCDIR): Add somsolib.h
(ALLDEPFILES): Add somsolib.c.
(somsolib.o): Add some dependencies.
* somread.c (som_symtab_read): Accept multiple section offsets.
All callers changed. Adjust all text symbols with the first
section offset.
* symfile.c (find_lowest_section): Enable this function. Add some
tie-breaking logic when sections have the same vma.
(syms_from_objfile): Use find_lowest_section rather than looking
for ".text" by name. Relax warning to only warn if the lowest
section is not a code section.
* config/pa/{hppabsd.mh, hppahpux.mh} (NATDEPFILES): Add somsolib.o
* config/pa/{nm-hppab.h, nm-hppah.h}: Include somsolib.h.
