Strengthen fields in struct sequence_stack and struct emit_status
gcc/
2014-08-26 David Malcolm <dmalcolm@redhat.com>
* function.h (struct sequence_stack): Strengthen fields "first"
and "last" from rtx to rtx_insn *.
(struct emit_status): Likewise for fields "x_first_insn" and
"x_last_insn".
* emit-rtl.h (get_insns): Remove now-redundant checked cast.
(set_first_insn): Add checked cast.
(get_last_insn): Remove now-redundant checked cast.
(set_last_insn): Add checked cast.
* config/m32c/m32c.c (m32c_leaf_function_p): Strengthen locals
"saved_first" and "saved_last" from rtx to rtx_insn *.
