I don't understand your comment Richard. Isn't it just something like this?
(define_peephole2
[(match_scratch:SI 2 "r")
(set (match_operand:SI 0 "memory_operand" "")
(match_operand:SI 1 "const_0_operand" ""))]
""
[(set (match_dup 2) (match_dup 1))
(set (match_dup 0) (match_dup 2))]
"")-- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41505
