3861 * ifcvt.c (cond_exec_changed_p): New static variable.
3862 (last_active_insn): New function, renamed from last_active_insn_p

3867 IFCVT_MODIFY_INSN. All callers updated.

3869 Handle case where we're processing an insn that is already
3870 conditional.
3871
3872 (noce_process_if_block): CE_INFO argument rather than
3873 multiple args containing the involved basic blocks. All callers
3874 changed.

3883 cond_exec_changed_p to TRUE.
3884
3885 (process_if_block): New code to handle multiple tests.
3886 (merge_if_block): Likewise.
3887 (find_if_header): New arg PASS. Changed to return the currently

3890 Call IFCVT_INIT_EXTRA_FIELDS.
3891 (block_jumps_and_fallthru_p): New function.
3892 (find_if_block): Discover opportunities to convert multiple tests.
3893 Add additional debugging output.
3894 Update the ce_info structure before returning.
3895
