(kinda o.t.) Oh Yes I'm quite sure of it -- Apple and IBM are working on gcc and feeding the changes back to the GNU teams, who are probably swamped. ;) So I bet it won't be seen in gcc34 yet, tho. And this work may also be going into IBM's 'enterprise' compiler (the US$3K version ;) . I believe the man page for gcc on Panther does show what the levels do at -O4 and -O5. (My G4 is at home, TPTB would have a hissy-fit if I brought it in. I have the Darwin CD for i386 based on Panther, here at work; maybe gcc is installed from it, and I can try posting its manpage somehow.) I have a feeling the higher -O levels won't show until/unless gcc itself is compiled for ppc platforms, y'know #ifdefs in the src. Else the patches for the GNU teams are in a long line for review. They're doing the work because IBM *really* want the G5 to be very-well supported. And not just for Apple. You see Sony & M$ have announced their next game consoles will be based on the G5. I'm hoping all gcc users will eventually see the benefits of their work. -- thx, Paul Seniura. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
