<p><a name="index-g_t_0040code_007bweakref_007d-directive-499"></a>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.

   <p>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.

   <p>The alias itself never makes to the symbol table, and is entirely handled
within the assembler.
