Detailed Description

template<typename T>
struct Fortran::lower::CallInterface< T >::PassedEntity

PassedEntity is what is provided back to the CallInterface user. It describe how the entity is plugged in the interface

Member Function Documentation

isSequenceAssociatedDescriptor()

template<typename T >

bool Fortran::lower::CallInterface< T >::PassedEntity::isSequenceAssociatedDescriptor

Is the dummy argument an explicit-shape or assumed-size array that must be passed by descriptor? Sequence association imply the actual argument shape/rank may differ with the dummy shape/rank (see F'2023 section 15.5.2.12), so care is needed when creating the descriptor for the dummy argument.

mayRequireIntentoutFinalization()

template<typename T >

bool Fortran::lower::CallInterface< T >::PassedEntity::mayRequireIntentoutFinalization

May the dummy argument require INTENT(OUT) finalization on entry to the invoked procedure? Provides conservative answer.

characteristics

template<typename T >

const Fortran::evaluate::characteristics::DummyArgument* Fortran::lower::CallInterface< T >::PassedEntity::characteristics

Initial value:

=
        nullptr

Pointer to the argument characteristics. Nullptr for results.

entity

template<typename T >

FortranEntity Fortran::lower::CallInterface< T >::PassedEntity::entity

What is the entity (SymbolRef for callee/ActualArgument* for caller) What is the related mlir::func::FuncOp argument(s) (mlir::Value for callee / index for the caller).
