Sender: news@mozo.cc.purdue.edu (USENET News) Message-ID: <Cs6H8t.pKL@mozo.cc.purdue.edu> Date: Wed, 29 Jun 1994 21:34:05 GMT Organization: Purdue University Lines: 11 I know I've read somewhere that FreeBSD initializes the FPU trap mask in an unusual way (something not masked that usually is), and that the mask needs to be changed for some math-intensive programs. The "port" of Octave on FreeBSD.cdrom.com includes a line which masks *all* FPU signals, but that's a bit extreme. Can anyone explain the FPU mask settings? Thanks, -- Ben Jackson, bj@cs.purdue.edu
