bfd/
* archures.c (bfd_mach_cpu32_fido): Rename to bfd_mach_fido.
* bfd-in2.h: Regenerate.
* cpu-m68k.c (arch_info_struct): Use bfd_mach_fido instead of
bfd_mach_cpu32_fido.
(m68k_arch_features): Use fido_a instead of cpu32.
(bfd_m68k_compatible): Reject the combination of Fido and
ColdFire. Accept the combination of CPU32 and Fido with a
warning.
* elf32-m68k.c (elf32_m68k_object_p,
elf32_m68k_merge_private_bfd_data,
elf32_m68k_print_private_bfd_data): Treat Fido as an
architecture by itself.
binutils/
* readelf.c (get_machine_flags): Treat Fido as an architecture
by itself.
gas/
* config/tc-m68k.c (m68k_archs, m68k_cpus): Treat Fido as an
architecture by itself.
(m68k_ip): Don't issue a warning for tbl instructions on fido.
(m68k_elf_final_processing): Treat Fido as an architecture by
itself.
include/elf/
* m68k.h (EF_M68K_FIDO): New.
(EF_M68K_ARCH_MASK): OR EF_M68K_FIDO.
(EF_M68K_CPU32_FIDO_A, EF_M68K_CPU32_MASK): Remove.
include/opcode/
* m68k.h (m68010up): OR fido_a.
opcodes/
* m68k-opc.c (m68k_opcodes): Replace cpu32 with
cpu32 | fido_a except on tbl instructions.
