DESCRIPTION

The C/C++ directive names are used below to explain their behaviors. These directives behave similarly in both C/C++ and Fortran.

The clone_always and clone_never directives specify functions or procedures that the compiler should always/never attempt to clone. If the directive is placed in the definition of the function, cloning is always/never attempted at every call site to name in the entire input file being compiled. If the directive is placed in a function other the definition, cloning is always/never attempted at every call to name within the specific function containing the directive.

The clone_always, clone_never directives control cloning of a procedure for the compilation of the whole input file.

Use compile options -hipaN or -OipaN where N is equal to or greater than 4 to enable cloning directives.
