* cpu-i960.c (MAX_ARCH): New macro.
(compatible): Use it in computing array bounds. Put comma after
last entry in array, for regularity.
(arch_info_struct): Adjust spacing for easier reading.
* coff-i960.c (howto_rellong, howto_iprmed, howto_optcall): Use
HOWTO macro.
start-sanitize-i960xl
* cpu-i960.c (XL): Define as bfd_mach_i960_xl.
(scan_960_mach): Recognize xl machine.
(MAX_ARCH): Define to be XL.
(compatible): Add XL row to array.
(arch_info_struct): Add XL entry.
* archures.c (bfd_mach_i960_xl): New macro.
* bfd-in2.h: Regenerated.
* coffcode.h (coff_set_arch_mach_hook): For F_I960XL, set machine
to bfd_mach_i960_xl.
(coff_set_flags): For bfd_mach_i960_xl, set F_I960XL.
end-sanitize-i960xl
