NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping
from older versions of FreeBSD, try WITHOUT_CLANG to bootstrap to the tip of
-head, and then rebuild without this option. The bootstrap process from
+stable/10, and then rebuild without this option. The bootstrap process from
older version of current is a bit fragile.
-NOTE TO PEOPLE WHO THINK THAT FreeBSD 10.x IS SLOW:
- FreeBSD 10.x has many debugging features turned on, in both the kernel
- and userland. These features attempt to detect incorrect use of
- system primitives, and encourage loud failure through extra sanity
- checking and fail stop semantics. They also substantially impact
- system performance. If you want to do performance measurement,
- benchmarking, and optimization, you'll want to turn them off. This
- includes various WITNESS- related kernel options, INVARIANTS, malloc
- debugging flags in userland, and various verbose features in the
- kernel. Many developers choose to disable these features on build
- machines to maximize performance. (To completely disable malloc
- debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely
- disable the most expensive debugging functionality run
- "ln -s 'abort:false,junk:false' /etc/malloc.conf".)
