True. We removed the kernel support for the 80386SX, DX and EX and = clones years ago. We kept the userland support for 80386 since it = lacked the compare and exchange instructions for a few years more, but = that too is many years out of the tree. The name i386 is more used to = mean x86-32, ia32, or any other way to designate the 32-bit version of = the architecture. Or the family of processors starting with 80386. > Robert >=20 >=20 >>=20 >>> we might even be a bit more aggressive >>> on getting rid of that old cruft. >>>=20 >>> the freebsd kernel should be tuned towards >>> the recent cpus. >>=20 >> This is already done. >>=20 >> Warner >>=20 >>>=20 >>> Is there anyone working on transactional memory? >>> ~eike >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>>=20 >>> On Dec 1, 2012, at 15:48 , Dimitry Andric wrote: >>>=20 >>>> On 2012-11-29 23:33, Jung-uk Kim wrote: >>>>> I'd like to remove i386 from bsd.cpu.mk on head.
