FYI: sparc-rtems does not build on 64-bit host

/* The word size used by BFD on the host.  This may be 64 with a 32

#define BFD_ARCH_SIZE @wordsize@

But:

static void
sparc_elf_append_rela_64 (bfd *abfd ATTRIBUTE_UNUSED,
                          asection *s ATTRIBUTE_UNUSED,
                          Elf_Internal_Rela *rel ATTRIBUTE_UNUSED)
{
#ifdef BFD64
  Elf64_External_Rela *loc64;

  loc64 = (Elf64_External_Rela *) s->contents;
  loc64 += s->reloc_count++;
  bfd_elf64_swap_reloca_out (abfd, rel, (bfd_byte *) loc64);
#endif
}

Without sparc64 configured in, bdf_elf64_swap_reloca_out is not available.

Hi Daniel,

> Without sparc64 configured in, bdf_elf64_swap_reloca_out is not available.

I have been using this as a local patch to work around this problem:

       ;;
   #ifdef BFD64

But I am not yet convinced that it is the right thing to do, and of 
course it would need to be extended to other sparc targets as well, so I 
have not yet applied it to the mainline.

Cheers
