next_cc0_user and prev_cc0_setter scaffolding
2014-08-19 David Malcolm <dmalcolm@redhat.com>
* rtl.h (next_cc0_user): Strengthen return type from rtx to
rtx_insn *.
(prev_cc0_setter): Likewise.
* emit-rtl.c (next_cc0_user): Strengthen return type from rtx to
rtx_insn *, adding checked casts for now as necessary.
(prev_cc0_setter): Likewise.
