struct CallLowering::OutgoingValueAssigner

Declaration

struct CallLowering::OutgoingValueAssigner : public ValueAssigner { /* full declaration omitted */ };

Description

Argument handling is mostly uniform between the four places that make these decisions: function formal arguments, call instruction args, call instruction returns and function returns. However, once a decision has been made on where an argument should go, exactly what happens can vary slightly. This class abstracts the differences. ValueAssigner should not depend on any specific function state, and only determine the types and locations for arguments.
