revert: loop.h (struct induction): Add multi_insn_incr.
* Back out this patch:
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.
