Debuggers need to know about the stack frame and so it already has became a part of the ABI, if we want or not. You may recall the great pain I went through to maintain compatibility in the past when changes were necessary for example to support the DSP ASE. But to some degree the stackframe is a function of hardware development which I don't control so I can only give a best effort type of guarantee ... Ralf
