Thanks. Remove the extra parentheses.

I must say I don't see the point of extra RTL predicates, but I'll let

Yes, that's what I disagree with. :-)
Actually to be a bit less pedantic, I'd say I agree with predicates for
every RTL expression in class RTX_OBJECT (REG, MEM, SUBREG, SYMBOL_REF
and a few others). I would even love to have SUBREG_REG_P for
GET_CODE (X) == SUBREG && GET_CODE (SUBREG_REG (X)) == REG
In the end it was SET_P and PLUS_P that I didn't like (though I know
they're quite frequent), and PARALLEL_P that I didn't feel the need for.
