List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 06 Nov 2017 19:49:58 -0000 Hello, I would like to have some feedback on my attempt to import OpenBSD code for cpow and clog: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221341 https://bugs.freebsd.org/bugzilla/attachment.cgi?id=187693 What happened to the alternative implementation mentioned in the thread below? And what had stopped the developers from just reusing the Net- or OpenBSD code? Far as I see, FreeBSD's msun source resembles those other libm's a lot anyway? https://lists.freebsd.org/pipermail/freebsd-numerics/2012-August/000028.html Kind regards, Mike
