--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
But what about vsib_address_operand, address_mpx_no_base_operand,
address_mpx_no_index_operand?
Even address_operand is used directly:
  [(prefetch (match_operand:P 0 "address_operand" "p")
             (const_int 1)
             (const_int 2))]
The comment above address_operand is definitely confusing, because when it is
used directly in the *.md (various ports), then the mode of the address is
passed to it, the comment above address_operand is confusing:
"Return 1 if OP is a valid memory address for a memory reference of mode MODE."
and memory_address_p it calls wants address of the MEM, not the address.
