      7 * On amd64 we have two 32bit ABIs - i386 and x32.  The latter
      8 * has bigger registers, so we use it for compat_elf_regset_t.
      9 * The former uses i386_elf_prstatus and PRSTATUS_SIZE/SET_PR_FPVALID
     10 * are used to choose the size and location of ->pr_fpvalid of
     11 * the layout actually used.
