Hi,
apparently there seems to be another reason copy_insn_1 can do quadratic
amount of work except for this one, I don't seem to be able to see any
however.  Just for sure, did you updated both cases of wrong recursion,
the EXPR_LIST I sent and the INSN_LIST hunk just bellow?
Otherwise probably adding a breakpoint on copy_insn_1 and seeing how it
manage to do so many recursions will surely help :)
