question about match_operand and vec_select

I noticed that the (vec_select:m ...) couldn't be matched by (match_operand:m ...).
For example:
(set (vec_select:HI (reg:V4QI r3)
(parallel [(const_int 0) (const_int 1)]))
(const_int 0x1122))
couldn't be matched by:
[(set (match_operand:HI 0 "register_operand" "=R")
(match_operand 1 "const_int_operand" "i"))]
Only the RTL templates which contained explicit (vec_select:HI ...) are matched.
Is the situation natural and right?
Thanks a lot.
