C++ (Cpp) index_for_IArgLocation Examples

Example #1

File: vframe_i386.cpp Project: ardeujho/self

oop* dummy_vframe::register_contents_addr(Location r) {
  fint i = index_for_IArgLocation(r);
  assert(SaveOutgoingArgumentsOfPatchedFrames, "I386 needs this");
  assert(i + 1  <  OutgoingArgsOfReturnTrapOrRecompileFrame->length(), "bounds");
  oop* argp = OutgoingArgsOfReturnTrapOrRecompileFrame->objs(i + 1);
  assert((*argp)->verify(), "checking arg");
  return argp;
}

Example #2

File: frame_i386.cpp Project: AdamSpitz/self

// this may not be a self frame ????
oop*  frame::location_addr_of_incoming_argument(Location r, RegisterLocator* rl) { 
  oop* bp = (oop*)my_bp();
  if (r == IReceiverReg)
    return bp + ircvr_offset;
  assert(is_IArgLocation(r), "???");
  fint i = index_for_IArgLocation(r);
  return bp + first_iarg_offset + i;
}
