I notice a slight newer version available, specifically referencing AMD64, which this box is: [root@kabini1, /etc, 10:15:12am] 630 % uname -a FreeBSD kabini1.local 9.3-RELEASE-p13 FreeBSD 9.3-RELEASE-p13 #0: Tue Apr 7 03:01:12 UTC 2015 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 [root@kabini1, /etc, 10:15:15am] 631 % grep -i gcc LIST.installed.txt gcc-4.8.4_3 GNU Compiler Collection 4.8 gcc-ecj-4.5 Eclipse Java Compiler used to build GCC Java [root@kabini1, /etc, 10:19:39am] 632 % grep -i gcc LIST.available.txt amd64-gcc-4.9.2_1 amd64-xtoolchain-gcc-0.1 I only use ports for the flash library, however I am wondering if there might be any performance improvement in recompiling some stuff locally, possibly with a compiler tuned/optimized for AMD64. Is that amd64-gcc-4.9.2.1 such an animal ? Is it stable/solid/fully tested & functional, or an alpha or beta version ? Binary compatible w/ packages from pkg ? I normally maintain *everything* on this box (except for flash support) using pkg (old Convex/SGI habits die hard, plus *much* quicker updates), however I am sporadically curious if there might be any performance to be picked up in locally compiling stuff, possibly including the kernel. This box is a quad-core jaguar-kabini based CPU & is not (yet) supported for acceleration under X11, but maybe other stuff might speed up some, who knows. TIA & have a good one .... -- William A.
