449   function in coff-sh.c for a description of what this does.  FIXME:
450   There is a lot of duplication here between this code and the COFF
451   specific code.  The format of relocs and symbols is wound deeply
452   into this code, but it would still be better if the duplication
453   could be eliminated somehow.  Note in particular that although both
454   functions use symbols like R_SH_CODE, those symbols have different
455   values; in coff-sh.c they come from include/coff/sh.h, whereas here
456   they come from enum elf_sh_reloc_type in include/elf/sh.h.  */
