(struct ecoff_backend_data): Move external debugging information
fields into a single field pointing to an ecoff_debug_swap
structure.
(ecoff_data_type): Move debugging information fields into a single
field pointing to an ecoff_debug_info structure.
* coff-alpha.c, coff-mips.c, ecoff.c: Corresponding changes.
(ecoff_mkobject_hook): New function.
(ecoff_new_section_hook, ecoff_sizeof_headers,
ecoff_compute_section_file_positions, ecoff_set_section_contents,
ecoff_write_object_contents): Handle dummy REGINFO section.
(ecoff_get_section_contents): New function to handle reading
REGINFO section.
* libecoff.h (ecoff_get_section_contents): Change from macro
definition to function prototype.
(ecoff_mkobject_hook): New prototype.
* coff-alpha.c (alpha_ecoff_mkobject_hook): Removed.
(alpha_ecoff_backend_data): Use ecoff_mkobject_hook.
* coff-mips.c (mips_ecoff_mkobject_hook): Removed.
(mips_ecoff_backend_data): Use ecoff_mkobject_hook.
sections with SEC_LOAD set, even if SEC_HAS_CONTENTS is clear.
(ecoff_write_object_contents): Don't set scnptr to zero just
because size of section is zero. Needed for Irix 4.0.5F.
alpha_ecoff_swap_reloc_{in,out}, alpha_bfd_reloc_type_lookup):
Read and write Alpha relocs. Can't process them yet.
* ecoff.c (ecoff_slurp_reloc_table): Recognize new reloc sections.
If the section does not already exist, create it.
objdump -r.
* coffswap.h: Added macros used when accessing several fields;
default is the same as before.
(coff_swap_aouthdr_{in,out}): Handle the Alpha ECOFF fields.
* coff-alpha.c: Defined macros to use the right sizes in
coffswap.h.
* libecoff.h: Backend information is now in target vector, not
BFD. Start of backend information is COFF backend information.
* coff-alpha.c, coff-mips.c: Changed accordingly.
* ecoff.c (ecoff_mkobject): New function.
(ARMAP_START): Changed into backend information, since Alpha uses
a different name.
(ecoff_slurp_armap): Don't overlay archive header.
* bfd.c: Include libcoff.h.
* 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* coff-msym.c: Removed; superseded by ecoffswap.h.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.
