of architectures, get the ELF EM_xxx code from the backend
information. Let the generic ELF target match any EM_xxx code not
matched by another ELF target. Call elf_backend_object_p to let
the backend do more checks and set global information.
* libelf.h (struct elf_backend_data): Added elf_machine_code and
elf_backend_object_p fields.
(struct bfd_elf_arch_map): Removed.
(bfd_elf_arch_map, bfd_elf_arch_map_size): Don't declare.
* elf32-target.h, elf64-target.h: Initialize elf_machine_code
field with ELF_MACHINE_CODE. Initialize elf_backend_object_p
field with elf_backend_object_p (if it is defined).
* elf32-gen.c, elf32-hppa.c, elf32-i386.c, elf32-i860.c,
elf32-m68k.c, elf32-m88k.c, elf32-mips.c, elf32-sparc.c,
elf64-gen.c (ELF_MACHINE_CODE): Defined.
* elf32-mips.c: Include ecoffswap.h to get ECOFF swapping
routines.
(mips_elf_object_p): Set the right machine number.
(mips_elf_ecoff_debug_swap): Defined.
(elf_backend_object_p): Defined to be mips_elf_object_p.
(elf_backend_ecoff_debug_swap): Defined to be
mips_elf_ecoff_debug_swap.
* elf.c (bfd_elf_arch_map, bfd_elf_arch_map_size): Removed.
* elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
for R_MIPS_26. Correct overflow detection requires matching the
upper four bits of the destination against the PC. From Ted Lemon
<mellon@pepper.ncd.com>.
* elf32-hppa.c (elf_hppa_reloc_type_lookup): Return type
should point to const data.
(struct elf_backend_data): Added elf_backend_ecoff_debug_swap
field. Removed unused write_relocs field.
* elf32-target.h: Adjusted elf_backend_data initialization
accordingly.
* elf64-target.h: Corrected elf_backend_data initialization to
fill in all fields and to set elf_64_p to 1.
* elfcode.h (bfd_section_from_shdr): If section is SHT_PROGBITS,
and the name starts with .debug, .line or .stab, set
SEC_DEBUGGING.
* elf32-target.h (TARGET_BIG_SYM, TARGET_LITTLE_SYM): Added
SEC_DEBUGGING to section_flags.
* elf64-target.h (TARGET_BIG_SYM, TARGET_LITTLE_SYM): Added
SEC_DEBUGGING and SEC_CODE to section_flags.
* bfd-in2.h: Updated.
* bfd-in.h: Added swapping routine declarations, and renamed them
from _do_* to bfd_*.
* libbfd.c: Renamed swapping routines from _do_* to _bfd_*.
* Changed all callers.
* libbfd.h, bfd-in2.h: Rebuilt.
