7.106 '.weakref ALIAS, TARGET'
==============================
This directive creates an alias to the target symbol that enables the
symbol to be referenced with weak-symbol semantics, but without actually
making it weak. If direct references or definitions of the symbol are
present, then the symbol will not be weak, but if all references to it
are through weak references, the symbol will be marked as weak in the
symbol table.
The effect is equivalent to moving all references to the alias to a
separate assembly source file, renaming the alias to the symbol in it,
declaring the symbol as weak there, and running a reloadable link to
merge the object files resulting from the assembly of the new source
file and the old source file that had the references to the alias
removed.
The alias itself never makes to the symbol table, and is entirely
handled within the assembler.
