When niter may be zero, return a COND_EXPR with the may_be_zero condition.
2010-05-28 Sebastian Pop <sebastian.pop@amd.com>
* tree-scalar-evolution.c (set_nb_iterations_in_loop): Inlined in the
only place it was called from.
(number_of_latch_executions): Do not return chrec_dont_know when the
may_be_zero is a runtime condition: instead, return a COND_EXPR
including the may_be_zero condition.
* cfgloop.h (struct loop): Add a note on COND_EXPRs to the comment
of nb_iterations.
* tree-ssa-loop-ivopts.c (contains_abnormal_ssa_name_p): Handle
COND_EXPRs.
* gcc.dg/vect/vect-outer-fir-lb.c: Un-XFAIL-ed.
