Seems to have been created by expand:

;; MEM[base: q, index: 0B] = MEM[base: p, index: 0B] + 10
(insn 75 73 76 (set (reg:SI 151)
        (mem:SI (plus:SI (const_int 0 [0x0])
                (reg/v/f:SI 144 [ p ])) [5 S4 A32])) -1 (nil)
    (nil))

The PLUS isn't in canonical form.

#define PRINT_OPERAND_ADDRESS(FILE, ADDR)  \
{ rtx addr = ADDR;                                                      \
  switch (GET_CODE (addr))                                              \
