 // Generate code for entering a JS function with the interpreter.
 // On entry to the function the receiver and arguments have been pushed on the
 // stack left to right.  The actual argument count matches the formal parameter
 // count expected by the function.
 //
 // The live registers are:
 //   o r4: the JS function object being called.
+//   o r6: the new target
 //   o cp: our context
 //   o pp: the caller's constant pool pointer (if enabled)
 //   o fp: the caller's frame pointer
 //   o sp: stack pointer
 //   o lr: return address
 //
 // The function builds a JS frame.  Please see JavaScriptFrameConstants in
 // frames-ppc.h for its layout.
 // TODO(rmcilroy): We will need to include the current bytecode pointer in the
 // frame.
