* config/alphaosf.mh (HDEFINES): Set to -DHPUX_CORE.
(HDEPFILES): Set to hpux-core.o.
* bfd-in2.h (union tdata): Add osf_core_data member.
* targets.c: If OSF_CORE is defined, add osf_core_vec to target list.
* Makefile.in (OPTIONAL_BACKENDS): Add osf-core.o.
(osf-core.o): New dependency.
* sco-core.c: Remove, replace by trad-core.c.
* trad-core.c: If HOST_STACK_START_ADDR is defined, use it.
* config/i386sco.mh: Use trad-core not sco-core.
* hosts/i386isc.h, config/i386isc.mh: Remove.
* configure.host: Use i386sco for isc.
* config/i386-sco.mt: Remove, identical to i386-coff.mt.
* config.bfd: Use i386-coff not i386-sco.
* ecoffswap.h: New file for ECOFF swapping functions which differ
only slightly for different targets.
* libecoff.h: Added prototypes for ecoff.c functions.
(ecoff_backend_data): New structure.
(ecoff_tdata): Added backend_data field. Changed external data
pointers to be PTR rather than to a particular struct.
(ecoff_symbol_struct): Moved in from coff-mips.c.
* coff-alpha.c, coff-mips.c: Moved common functions into ecoff.c.
Added ECOFF backend structures. Include ecoffswap.h.
* coff-msym.c: Removed; superseded by ecoffswap.h.
* bfd.c: Include coff/internal.h.
* Makefile.in (BFD_LIBS): Removed coff-mips.o and coff-msym.o.
Added ecoff.o.
(BFD64_BACKENDS): Added coff-alpha.o.
(CFILES): Removed coff-msym.c. Added ecoff.c.
(bfd.o): Added dependency on $(INCDIR)/coff/sym.h.
(coff-mips.o): Added dependency on ecoffswap.h and coff/ecoff.h.
(ecoff.o, coff-alpha.o): New targets.
(coff-msym.o): Removed target.
* nlm-target.h: New file, merged from nlm{32,64}-target.h
* libnlm.h (NLM_ARCH_SIZE): Define to ARCH_SIZE.
* nlm.c (ARCH_SIZE): Remove define to zero.
* nlm32-gen.c (ARCH_SIZE): Define to 32.
* nlm32-gen.c (JUMP_TABLE_PREFIX): Define to nlm32.
* nlm{32,64}-gen.c (nlm-target.h): Include.
* targets.c, libnlm.h, nlm.c, nlm{32,64}-gen.c, nlm{32,64}.c,
nlmcode.h: Convert prefixes from bfd_nlm<size> to just
nlm<size>, and use macros select size.
* libecoff.h: New file. Defines ECOFF backend data for gdb.
* coff-mips.c: Now includes libecoff.h.
(ecoff_data_type): Moved to libecoff.h.
(ecoff_slurp_symbolic_info): Made globally visible so that gdb can
call it. If there is ever another ECOFF target, this and the
swapping functions should be accessed via an ECOFF specific target
vector.
Makefile.in (coff-mips.o): Depends on libecoff.h.
