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

	bfd_get_symtab_upper_bound.

* targets.c (bfd_target): Added relocateable argument to

	* bfd-in.h (JUMP_TABLE): Added _bfd_seclet_link.
	* seclet.c (rel, seclet_dump_seclet): Added relocateable argument
	and boolean return value.  Made static.

	relocateable argument.

918356b902 Use struct bfd_seclet * rather than bfd_seclet_type in prototypes to 
avoid requiring seclet.h before libcoff.h.

075caafd65 These changes cut the size of libbfd.a on a Sun4 by about 11%. 
Somewhat more could be done.

Fri Jan  8 15:47:53 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

	* coffcode.h: Moved many generic functions into coffgen.c.  Moved
	swapping functions into coffswap.h for ECOFF use.  Moved
	relocation functions, only used by h8300 and z8k, into reloc16.c.
	Added hooks for coffgen.c functions to backend data structure, and
	added hook functions.  Still more could be done.
	* coffswap.h: New file to hold COFF swapping routines.
	* coffgen.c: New file to hold generic COFF functions.
	* reloc16.c: New file to hold h8300 and z8k specific relocation
	functions.
	* libcoff-in.h: Added declarations for functions in coffgen.c.
	* libcoff.h: Rebuilt to incorporate changes.
	* coff-h8300.c: Function name changes.
	* coff-z8k.c: Function name changes.  Use coff_reloc16_extra_cases
	hook rather than defining EXTRA_CASES.
	* Makefile.in: Build new files coffgen and reloc16.  Added
	dependencies of coff-*.o on coffswap.h and seclet.h.
