+ * insn-addr.h (insn_addresses_new): Strengthen param "insn" from
+ rtx to rtx_insn *.
+ * config/s390/s390.c (s390_split_branches): Eliminate top-level
+ local rtx "tmp", in favor of new local rtx "mem" and rtx_insn *
+ "set_insn".
+ (s390_mainpool_finish): In three places, split out a local rtx
+ "insn" into a local rtx - "set" or "pat" - and a rtx_insn *
+ "insn". Strengthen local "pool_end" from rtx to rtx_code_label *
+ and split another local rtx "insn" out into rtx "pat" and
+ rtx_insn * "insn".
+ * config/sh/sh.c (output_branchy_insn): Rather than working
+ directly on operands[9], introduce local rtx_code_label *
+ variables named "lab" in two places, working on them, and then
+ assigning them to operands[9], so that the intervening operations
+ are known by the type system to be on insns.
+

* rtl.h (INSN_HAS_LOCATION): Strengthen param from const_rtx to
const rtx_insn *.
