reload1.c (reload_as_needed): Accept dumpfile argument, pass it to emit_reload_insns.
* reload1.c (reload_as_needed): Accept dumpfile argument,
pass it to emit_reload_insns.
(emit_reload_insns): Add new dumpfile argument. If non-null
then dump the reloads for each insn into the dumpfile.
(reload): Pass dumpfile to reload_as_needed.
