// This file defines the (internal) constant folding interfaces for LLVM. These
|
|
// interfaces are used by the ConstantExpr::get* methods to automatically fold
|
|
// constants when possible.
|
|
//
|
|
// These operators may return a null object if I don't know how to perform the
|
|
// specified operation on the specified constant types.
