9d14250f9d * som.c (som_slurp_string_table): Allocate the strings with malloc
since they're free'd by free_cached_info.
        (som_slurp_symbol_table): Similarly for the symbol table.

f977e865cb * som.c (som_get_section_contents): New function. Do not try
to actually read data from a section that doesn't have either
        SEC_LOAD or SEC_DEBUGGING set (eg $BSS$) just return true.

250578363e * libbfd.c (bfd_read): Set bfd_error as appropriate for a short
read. (bfd_error_system_call or bfd_error_file_truncated).

        * som.c: Do not blindly set bfd_error_system_call after a
        failing bfd_read, bfd_write, or bfd_seek.  In a few places
        (like som_object_p) override the error status set by bfd_read.

        * aix386-core.c, aout-encap,c archive.c, bout.c: Likewise.

        * som.c: Check return values from several bfd_{seek,read,write}
        calls that we just assumed were not failing.

c2e1207b3a * som.c (bfd_section_from_som_symbol): Only to do the value
comparison for function symbols within executables.

c05d2d43a0 * som.c (bfd_section_from_som_symbol): Renamed from
som_section_from_subspace_index.  Pass in a native SOM symbol.
        For executables, iterate through the sections to find out
        which contains the symbol's address rather than using the
        symbol_info field.  (symbol_info has a different meaning for
        dynamicly linked executables.)

517a6af632 * som.c (som_begin_writing): Fix braino (one call to align
space/subspace data was done unconditionally rather than
        just for executables.)
