|
+ * HISTORY
|
||||||
|
+ * 09-Mar-12 Michael Ellerman <michael@ellerman.id.au>
|
||||||
|
+ * 64-bit implementation, copied from 32-bit.
|
||||||
|
+ * 07-Sep-05 (py-dev mailing list discussion)
|
||||||
|
+ * removed 'r31' from the register-saved. !!!! WARNING !!!!
|
||||||
|
+ * It means that this file can no longer be compiled statically!
|
||||||
|
+ * It is now only suitable as part of a dynamic library!
|
||||||
|
+ * 14-Jan-04 Bob Ippolito <bob@redivi.com>
|
||||||
|
+ * added cr2-cr4 to the registers to be saved.
|
||||||
|
+ * Open questions: Should we save FP registers?
|
||||||
|
+ * What about vector registers?
|
||||||
|
+ * Differences between darwin and unix?
|
||||||
|
+ * 24-Nov-02 Christian Tismer <tismer@tismer.com>
|
||||||
|
+ * 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.
|
||||||
|
+ * 04-Oct-02 Gustavo Niemeyer <niemeyer@conectiva.com>
|
||||||
|
+ * Ported from MacOS version.
|
||||||
|
+ * 17-Sep-02 Christian Tismer <tismer@tismer.com>
|
||||||
|
+ * 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 <gerd.woetzel@GMD.DE>
|
||||||
|
+ * slightly changed framework for sparc
|
||||||
|
+ * 29-Jun-02 Christian Tismer <tismer@tismer.com>
|
||||||
|
+ * Added register 13-29, 31 saves. The same way as
|
||||||
|
+ * Armin Rigo did for the x86_unix version.
|
||||||
|
+ * This seems to be now fully functional!
|
||||||
|
+ * 04-Mar-02 Hye-Shik Chang <perky@fallin.lv>
|
||||||
