(md_pseudo_table): Add pseudo-ops to set the current machine type.
        (md_begin): Default to mn10300 mode.
        (md_assemble): Only accept instructions for the core mn10300
        chip and the active machine type.

        for "xrN" registers.

* config/tc-mn10300.c (r_registers): Add missing registers.
        (xr_registers): New set of registers.
        (xr_register_name): New function.
        (md_assemble): Handle XRREG and PLUS operands.  Tweak handling of

        * config/tc-mn10300.c (mn10300_insert_operand): Do not hardcode the
        shift amount for a repeated operand.  The shift amount for the
        repeated copy comes from the size of the operand.

a405bb3eb0 * config/tc-mn10300.c (md_assemble): Don't use any MN10300 specific
relocs anymore.  Tweak fx_offset for pc-relative relocs.

d9a9c18fad * config/tc-mn10300.h (DIFF_EXPR_OK): Don't define this.

        pc-relative relocs.
        * config/tc-mn10300.c (md_begin): Set linkrelax.
        (md_assemble): Create fixups as needed.
        (md_apply_fix3): Gut.  It shouldn't ever get called anymore.
First stab at fixups/relocs.

7f02192d13 * config/tc-mn10300.c (md_assemble): Handle MN10300_OPERAND_REG_LIST.
So GCC can use movm in prologue/epilogues.

43d695a1e9 * config/tc-mn10300.c (mn10300_insert_operand): Provide prototype
via PARAMS.

bdd91d4f41 * config/tc-mn10300.c (mn10300_insert_operand): Shift low part
of a MN10300_OPERAND_SPLIT operand by operand->shift.

cdde2f5cee * config/tc-mn10300.c (mn10300_insert_operand): Handle
MN10300_OPERAND_SPLIT.
For handling of 32bit operands.

bfe5059c70 * config/tc-mn10300.c (md_assemble): Insert operands into
the extension part of the instruction if necessary.
        (mn10300_insert_operand): Accept pointer to extension word
        argument.  Make insn a pointer argument too.  Return type
        is now void.  All callers changed.
So we can correct insert operands into any instruction except those
which have 32bit operands.

68328dc6bd * config/tc-mn10300.c (mn10300_insert_operand): Handle
repeated register operands.
For mov imm8,dn
    mov imm8,an
    cmp imm8,dn
    cmp imm8,an

The register appears twice in the bit pattern...  Egad.

are 7 bytes long.  Write out instructions in big-endian format.

ae1b99e42d Grrr. The mn10200 and mn10300 are _not_ similar enough to easily support
with a single generic configuration.  So break them up into two different
configurations.  See the individual ChangeLogs for additional detail.
