They are for different fields in anycase. So that something is set in the upper-half of the word. These locations (mc_fpformat and mc_ownedfp) were previously occupied by FPU control and status words which are only 16 bits. So in case an older application/library (like libc_r) managed to save a FP control or status word in these locations, it couldn't possibly match something bigger than 16 bits. -- Dan Eischen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
