Abstract:
A return stack buffer (RSB) is modified such that each entry comprises two or more address slots. When a function is called, the address following the function call is pushed to the RSB and stored in a selected one of the address slots in a top entry in the RSB. One or more pointer bits within the entry are set to indicate which slot the address was stored in.
