Well, your commit has pre-empted any discussion on whether there would have been a better kludge. Oh well. Concerning coshl, sinhl, and tanhl. I had integrated bde's code into msun and prepared a patch to commit over a week ago. Unfortunately, my testing on sparc64 revealed a few issues with tanhl, and Bruce and I are still discussing the fix. PS: I have working erfl and erfcl for ld80 archs. I'm still testing and refining the code. It turns out that computing the needed rational approximation is fairly difficult (at least for me). -- Steve _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
