I sent a copy directly to Justin, but I do not wish to send a 722 page PDF file to everybody on the mailing list. If you wish to get a copy by e-mail, please, request for one in a separate personal e-mail, not on the mailing list. I guess the document should be available also on the IBM web site. The title of the document is... IBM PowerPC Microprocessor Family: The Programming Environment Manual for 32 and 64-bit Microprocessors Version 2.3 March 31, 2005 The detail about sprg0 is on page 75/722 in a table at the bottom of the page. --jau
