Description of SDTypeProfile

Hi,

A piece of code in a target description file:

def SDTIntBinOp : SDTypeProfile<1, 2, [ // add, and, or, xor, udiv, etc.
SDTCisSameAs<0, 1>, SDTCisSameAs<0, 2>, SDTCisInt<0>
]>;

May I understand “SDTCisSameAs<0, 1>, SDTCisSameAs<0, 2>, SDTCisInt<0>” as below?

(Z = X + Y, for example);

Z:0
X:1
Y:2
X has same type as Z

Y has same type as Z
Z is a integer

Thanks

Hello

May I understand "SDTCisSameAs<0, 1>, SDTCisSameAs<0, 2>, SDTCisInt<0>" as
below?

Yes, one result, two operands. The result is integer and type of
operands are same as the result.
