From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mark Kettenis To: gdb-patches@sourceware.cygnus.com Subject: [PATCH] FreeBSD/Alpha support Date: Wed, 31 May 2000 13:32:00 -0000 Message-id: <200005312032.e4VKWRG16903@delius.kettenis.local> X-SW-Source: 2000-05/msg00496.html I checked in support for FreeBSD/Alpha. This is tested on FreeBSD 5.0-CURRENT, but it should work on FreeBSD 4.x just as well. I'll put some blurp in the NEWS file (which reminds me that I still have to do this for FreeBSD/i386 too).
