Hi @nsjian ,
This question was related to SVE support,
Function vRegOper::type() always returns Type::VECA.
Type::VECA is initialized as maximal sized Scalable vector i.e. its size should be 2048 bit.  For a MachTypeNode having vReg as its def operand, will the def operand's type always match the bottom_type() of MachTypeNode?
