I think it should be investigated which packages could be compiled by icc s= ince intel are now providing it for free for non-commercial use. I did some test= s with it and whetstone (classic fpu benchmark from the 1970's) doubled in speed compared= to gcc on a P4, and it was about 75% faster on an Athlon-XP. Now float-point isn't everything b= ut from my experience icc generally produces better optimized code than gcc unless the applicatio= n has been hand-tuned (like mplayer). I tried installing gentoo with CC=3Dicc once but I had problems with many e= builds so I dropped that idea. At the moment extremely few ebuilds support icc. //David Holm On 13 Aug 2003 15:38:21 +0200 Philippe Lafoucri=E8re wrote: > http://articles.linmagau.org/modules.php?op=3Dmodload&name=3DSections&fil= e=3Dindex&req=3Dviewarticle&artid=3D227&page=3D1http://articles.linmagau.or= g/modules.php?op=3Dmodload&name=3DSections&file=3Dindex&req=3Dviewarticle&a= rtid=3D227&page=3D1 --=.9UtCL.7zI_5wdP Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (FreeBSD) iD8DBQE/OkojxVDe1wIoqX0RAg91AKCDAyqnUnMt/K9/EqAo2trgf8kJ7gCgoqLI hxeU6YYTF8sd1wo+GRqJUk0= =OZP3 -----END PGP SIGNATURE----- --=.9UtCL.7zI_5wdP--
