Changes to let BFD return an error indication from get_symtab_upper_bound, bfd_canonicalize_symtab, bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc. They now return long instead of unsigned int, and use -1 to indicate an error. Along the way, rename get_symtab_upper_bound to bfd_get_symtab_upper_bound. * bfd.c (bfd_get_reloc_upper_bound): Return long, and -1 on errors. (bfd_canonicalize_reloc): Likewise. * syms.c (bfd_get_symtab_upper_bound): Renamed from get_symtab_upper_bound. * targets.c (bfd_target): Renamed _get_symtab_upper_bound to _bfd_get_symtab_upper_bound, and changed it and _bfd_canonicalize_symtab and _get_reloc_upper_bound and _bfd_canonicalize_reloc to all return long. * aoutx.h (NAME(aout,get_symtab)): Return long, and -1 on errors. (NAME(aout,canonicalize_reloc)): Likewise. (NAME(aout,get_reloc_upper_bound)): Likewise. (NAME(aout,get_symtab_upper_bound)): Likewise. * bout.c (b_out_canonicalize_reloc): Likewise.
