* elfxx-sparc.h: New file. * Makefile.in (BFD32_BACKENDS): Add elfxx-sparc.lo (BFD32_BACKENDS_CFILES): Add elfxx-sparc.c (elfxx-sparc.lo): New rule. (elf32-sparc.lo): Add elfxx-sparc.h dependency. (elf64-sparc.lo): Likewise. * configure.in (bfd_elf32_sparc_vec): Add elfxx-sparc.lo (bfd_elf64_sparc_vec): Likewise. * configure: Regenerate. * elf32-sparc.c: Remove common code now in elfxx-sparc.c * elf64-sparc.c: Likewise, also use elf64_sparc_*() naming which is more consistent with elf32-sparc.cmsnyder-tracepoint-checkpoint-branch
