    Description

      When using ubsan we run into the following error :

      src/hotspot/share/interpreter/templateTable.cpp:62:3: runtime error: call to function TemplateTable::nop() through pointer to incorrect function type 'void (*)(int)'
      templateTable_x86.cpp:258: note: TemplateTable::nop() defined here

         ... (rest of output omitted)

      Reason is a mismatch of the generator function typedef compared to the real interface.
      The generator function is

        typedef void (*generator)(int arg);

      But TemplateTable::nop() is 'void (*)(int)' .
