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 *. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@214537 138bc75d-0d04-0410-961f-82ee72b054a4
