AllocaInst * AllocaInst::clone (  )  const [virtual]

clone() - Create a copy of 'this' instruction that is identical in all ways except the following: The instruction has no parent The instruction has no name

bool AllocaInst::isStaticAlloca (  )  const

isStaticAlloca - Return true if this alloca is in the entry block of the function and is a constant size. If so, the code generator will fold it into the prolog/epilog code, so it is basically free.
