In the LLVM Programmers Manual it states:
"One important aspect of LLVM is that there is no distinction between an
SSA variable and the operation that produces it. Because of this, any
reference to the value produced by an instruction (or the value available
as an incoming argument, for example) is represented as a direct pointer
to the _class_ that represents this value. Although this may take some
getting used to, it simplifies the representation and makes it easier to
Shouldn't it be "instance" instead of "class"?
