* flow.c (REVERSE_CONDEXEC_PREDICATES_P): Use the whole comparison, not
just the codes, call reversed_comparison_code ().
(ior_reg_cond): Update arguments to REVERSE_CONDEXEC_PREDICATES_P.
(not_reg_cond): Use reversed_comparison_code.
(and_reg_cond): Likewise.
* ifcvt.c (cond_exec_process_if_block): Likewise.
* doc/tm.texi (REVERSE_CONDEXEC_PREDICATES_P): Update documentation.
