/*
* this is the internal transfer function.
*
* HISTORY
* 24-Nov-02 Christian Tismer <[email protected]>
* needed to add another magic constant to insure
* that f in slp_eval_frame(PyFrameObject *f)
* STACK_REFPLUS will probably be 1 in most cases.
* gets included into the saved stack area.
* 26-Sep-02 Christian Tismer <[email protected]>
* again as a result of virtualized stack access,
* the compiler used less registers. Needed to
* explicit mention registers in order to get them saved.
* Thanks to Jeff Senn for pointing this out and help.
* 17-Sep-02 Christian Tismer <[email protected]>
* after virtualizing stack save/restore, the
* stack size shrunk a bit. Needed to introduce
* an adjustment STACK_MAGIC per platform.
* 15-Sep-02 Gerd Woetzel <[email protected]>
* slightly changed framework for sparc
* 01-Mar-02 Christian Tismer <[email protected]>
* Initial final version after lots of iterations for i386.
