X-BeenThere: freebsd-hackers@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Technical Discussions relating to FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 23 Mar 2009 16:54:49 -0000 Hello: I'm working with building the Boost libraries and Boost.Math has long double support stubbed out for FreeBSD (personally I don't need it but..). I believe looking at some historical threads about this over the weekend and a lot of it was due to compiler GNUish bugs handling long double math (I believe Bruce Evans had some patches at one point but mentioned it was still crappy). Can someone speak if the current compiler/BSD flavors support long double math on a 64-bit capable CPU (LM=1)? Thanks! -aps
