CallArgsDescriptor * CallArgsDescriptor::get (  const MachineInstr *  MI  )  [static]

CallArgsDescriptor::get - Mechanism to get the descriptor for a CALL MachineInstr. We get the LLVM CallInst from the return-address register argument of the CALL MachineInstr (which is explicit operand #2 for indirect calls or the last implicit operand for direct calls). We then get the CallArgsDescriptor from the MachineCodeForInstruction object for the CallInstr. This is roundabout but avoids adding a new map or annotation just to keep track of CallArgsDescriptors.
