Re: Dwarf changes

There are a few places where you will need to add dwarf support:

  * In your assembler function that generates an instruction (usually
    md_assemble or one of its subroutines) you should call dwarf2_emit_insn
    to let the dwarf code know how many bytes have been generated.

  * In the binutils/readelf.c source file you should make sure that any of
    the relocations that you generate against DWARF sections are covered
    by one of the is_32bit_abs_reloc() ... is_none_reloc() functions.

That should be it.  Running the testsuites may expose a couple of places 
that I have forgotten however.

Cheers
