| |
| <a name="index-weakref-directive"></a> |
| <p>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> |
| <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> |
| <p>The alias itself never makes to the symbol table, and is entirely handled |
| within the assembler. |
