Re: New port created but need advice when linking.

Sorry and thanks. LD shows support for both ports, but now I get this
error.

mc9s12x-elf-ld  --defsym _start=0800 -o test.elf xgate.o
mc9s12x-elf-ld: mc9xgate architecture of input file `xgate.o' is
incompatible with mc9s12x output

I did a bit of reading saying it's the archures.c file where they are
grouped and deemed compatible/incompatible.  These lines didn't seem to do
the trick.

My bfd.h file in my build directory reads

"
  bfd_arch_mc9s12x,   /* Motorola S12X */
  bfd_arch_mc9xgate,   /* Motorola S12X Xgate Co Processor*/
#define bfd_mach_mc9s12x       1
#define bfd_mach_mc9xgate      2
"

I also added this to my cpu- file.

const bfd_arch_info_type bfd_mc9xgate_info =
{
    16, /* 16 bits in a word */
    32, /* 16 bits in an address */
    8,  /* 8 bits in a byte */
    bfd_arch_mc9xgate,
    bfd_mach_mc9xgate,
    "mc9xgate",
    "mc9xgate",
    4, /* section alignment power */
    TRUE,
    bfd_default_compatible,
    bfd_default_scan,
    0,
};

const bfd_arch_info_type bfd_mc9s12x_arch =
{
    16, /* 16 bits in a word */
    32, /* 16 bits in an address */
    8,  /* 8 bits in a byte */
    bfd_arch_mc9s12x,
    bfd_mach_mc9s12x,
    "mc9s12x",
    "mc9s12x:mc9xgate",
    4, /* section alignment power */
    TRUE,
    bfd_default_compatible,
    bfd_default_scan,
    &bfd_mc9xgate_info,
};


But I still get

"mc9s12x-elf-ld: mc9xgate architecture of input file `xgate.o' is 
incompatible with mc9s12x:mc9xgate output"
