Some ports (eg. tcl*) require fpsetmask for build. But it has not been implemented yet on alpha. First, I thought the exception mask can be specified by FP_CR register, but none of currently avaiable CPUs don't seem to support the feature. Then I found the software completion is done in /sys/alpha/alpha/fp_emulate.c and we can specify the exception handing by setting proc->u_pcb.pcb_fp_control. My question is how I can set the variable, do we need a new system call for it? /\ Hidetoshi Shimokawa \/ simokawa@sat.t.u-tokyo.ac.jp PGP public key: finger -l simokawa@sat.t.u-tokyo.ac.jp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
