◆ emitAbstract() [1/2]

mlir::Attribute ConstantEmitter::emitAbstract ( const Expr * e,
QualType destType )

Emit the result of the given expression as an abstract constant, asserting that it succeeded.

This is only safe to do when the expression is known to be a constant expression with either a fairly simple type or a known simple form.
