-  <dd>This attribute indicates that the function should be 'hotpatchable',
-      meaning the function can be patched and/or hooked even while it is
-      loaded into memory. On x86, the function prologue will be preceded

   <dd>This attribute suppresses lazy symbol binding for the function. This
