I might try a (quasi-)weekly tarball sometime (it's on a mirror I can reach; can't do CVS here). Where might your builds be at, if I may ask? >For those that do not know, the entire middle-end and much >of the back-end of GCC has been re-written in 3.5. This is interesting. I do know Apple & IBM are coordinating work on GCC -- they *really* want the G5 chip to be the best supported fastest system going. FWIW at home I just got started using IBM's XL C/++ and FORTRAN for OSX compilers, yeah the US$3,000.- ones. ;) No I can't afford to buy them: they let you try 'em out for 60 days. Don't tell IBM there's a way to get their July 2004 updates applied on top of the trial pkgs. ;) They will support both G4 & G5. Flavors for AIX, Linux, and bigiron. Intending to support OpenMP, too. The massive speedups are with a G5 of course, but my G4 is showing a bit of muscle also. And true to IBM (I've been a mainframe programmer here for 27+ years), XL has its own vernacular, but they do provide wrappers (set CC=gxlc & CXX=gxlc++) that are suppose to translate GNUisms to its own parms (not too well IMO tho). XL can be interwoven with XCode, too. Some people/projects are patching apps makefiles to let XL compile them cleanly. I'm hoping their work here will show up in GCC sometime, who knows maybe in 3.5? <http://www-306.ibm.com/software/awdtools/vacpp/features/xlcpp-mac.html>; (I'm not a sales rep nor own stock yadda yadda yadda ;) Not much pickin's if I use my G4 to help on FreeBSD/PPC, tho... >-- >Steve -- thx, Paul Seniura.
