	Tue Dec  7 19:22:06 1999  Richard Henderson  <rth@cygnus.com>
          * loop.h (struct induction): Add multi_insn_incr.
          * loop.c (basic_induction_var): New multi_insn_incr argument.
          Set it if we search back through previous insns for the biv.
          (record_biv): New multi_insn_incr argument; fill in struct induction.
          (strength_reduce): Discard an iv with multiple bivs, any of
          which require multiple insns to increment.

	* loop.c (check_insn_for_bivs): Remove bits copied from above patch.
