Detailed Description

CalleeInterface only provides the helpers needed by CallInterface to abstract the specificities of the callee side.

Member Function Documentation

◆ addEntryBlockAndMapArguments()

mlir::func::FuncOp Fortran::lower::CalleeInterface::addEntryBlockAndMapArguments ( )

Add mlir::func::FuncOp entry block and map fir block arguments to Fortran dummy argument symbols.

◆ getProcedureSymbol()

const Fortran::semantics::Symbol * Fortran::lower::CalleeInterface::getProcedureSymbol ( ) const

Return the procedure symbol if this is a call to a user defined procedure.

◆ isIndirectCall()

bool Fortran::lower::CalleeInterface::isIndirectCall ( ) const

inline

On the callee side it does not matter whether the procedure is called through pointers or not.

◆ requireDispatchCall()

bool Fortran::lower::CalleeInterface::requireDispatchCall ( ) const

inline

On the callee side it does not matter whether the procedure is called through dynamic dispatch or not.
