I don't think this is true? Book I compatible PowerPC's have had a "no-executable" bit in the page protection flags since the dark ages.. see page 7-38 and 7-39 of the 'Programming Environments Manual for 32-Bit Microprocessors'.. this document predates even the G3. As far as the documentation goes, you can make the page readable and writable to the LSU, but the N bit causes the instruction fetch to cause a machine check. That's pretty "not-executable" to me at least :) -- Matt Sealey <[EMAIL PROTECTED]> Manager, Genesi, Developer Relations -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
