-// Purpose:
-//   Representation of each machine instruction.
-//
-//   MachineOpCode must be an enum, defined separately for each target.
-//   E.g., It is defined in SparcInstructionSelection.h for the SPARC.

-//  There are 2 kinds of operands:

-//  (1) Explicit operands of the machine instruction in vector operands[]

-//  (2) "Implicit operands" are values implicitly used or defined by the

-//      a CALL (if any), and return value of a RETURN.
