+       * 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.
