* config/sh/sh.c (register_sh_passes, sh_option_override,
sh_print_operand, prepare_move_operands,
sh_can_follow_jump): Remove TARGET_SH1 checks.
* config/sh/sh.h (TARGET_VARARGS_PRETEND_ARGS, VALID_REGISTER_P,
PROMOTE_MODE): Likewise.
* config/sh/sh.md (adddi3, addsi3, subdi3, subsi3, andsi3,
movdi): Likewise.
