    NEGDI2_LIBCALL, INIT_TARGET_OPTABS, MASK_STRICT_ALIGN): Define.
    (PREDICATE_CODES): Include new predicates.
    (RTX_COSTS): Handle UMOD and UDIV.  Tune MULT for v850e.
    (TARGET_SWITCHES):  Add strict-align.
    (TARGET_STRICT_ALIGN): New.
    (MASK_DEFAULT, STRICT_ALIGNMENT):  Redefine.
    * config/v850/t-v850 (MULTILIB_OPTIONS, MULTILIB_DIRNAMES):
    Define.
    (LIB1ASMFUNCS): Add v850_negdi2, v850_cmpdi2, v850_ucmpdi2,
    v850_muldi3.
    * config/v850/lib1funcs.asm (L_callt_save_r2_r29, L_return_r2_r29,
    L_callt_save_r2_r31, L_return_r2_r31,
    L_save_all_interrupt): Change addi to add.
    (L_save_interrupt, L_return_interrupt): Rework.
    (__return_r31):  Correct .size directive.
    (mulsi3, divsi3, udivsi3, umodsi3, modsi3): Tune for v850e.
    (v850_negdi2, v850_cmpdi2, v850_ucmpdi2, v850_muldi3):
    New routines.
    * config/v850/v850.c (expand_prologue): Call
    gen_callt_save_interrupt, gen_callt_restore_all_interrupt,
    gen_callt_return_interrupt and gen_callt_save_all_interrupt.
    (reg_or_int9_operand): New predicate.
    (reg_or_const_operand): New routine.
    * config/v850/v850.md (return_interrupt): Changed from
    restore_interrupt.
    (callt_save_all_interrupt): Changed from save_all_interrupt_v850e.
    (callt_save_interrupt): Change save sequence.
    (callt_return_interrupt): New.
    (save_interrupt): Don't use runtime function for LONG_CALLS
    and TARGET_PROLOG_FUNCTION.
    (save_all_interrupt): Likewise.
    (mulsi3): Use new predicate.
    (moviscc): Disallow some combination of constants.
    Fix define_split for sasf insns, so that it will not generate bad
    code if operand0 and operand5 are the same.
    * config/v850/v850-protos.h: Prototype new predicates.
