   9 // This transformation is designed for use by code generators which do not yet
  10 // support stack unwinding.  This pass converts 'invoke' instructions to 'call'
  11 // instructions, so that any exception-handling 'landingpad' blocks become dead
  12 // code (which can be removed by running the '-simplifycfg' pass afterwards).
