description:
slicc: enable overloading in functions not in classes
For many years the slicc symbol table has supported overloaded
functions in
external classes. This patch extends that support to functions that
are not
part of classes (a.k.a. no parent). For example, this support allows
slicc
to understand that mapAddressToRange is overloaded and the NodeID is an
optional parameter.
