interface of a unit, or forward declared, and then the implementation turns
out to be external. We now properly generate a wrapper routine at the
Pascal level for the original declaration that calls through to the
external routine
git-svn-id: trunk@31285 -
a single external symbol may be used with multiple declarations that
have different types:
o always declare an alias with the Pascal-mangled name that aliases the
external symbol, with the type of that Pascal declaration
o if the external symbol is not actually external but in the same unit,
we will determine the type of that symbol via its declaration and
insert type conversions in the alias declarations in case they use a
different type
o if it is external (so there is no declaration from which we can determine
its real type) and there are nevertheless multiple aliases for it with
different types, we just take the type of the first alias and insert
type conversions for the other aliases. LLVM will take care of the
conflicting types in multiple modules when performing WPO if necessary
