/* This file implements a few interface functions which are provided
for use with struct demangle_component trees. These functions are
declared in demangle.h. These functions are closely tied to the
demangler code in cp-demangle.c, and other interface functions can
be found in that file. We put these functions in a separate file
because they are not needed by the demangler, and so we avoid
having them pulled in by programs which only need the
demangler. */
