Author: emaste Date: Mon Jan 12 18:13:38 2015 New Revision: 277078 URL: https://svnweb.freebsd.org/changeset/base/277078 Log: Remove duplicate copies of trivial getcontextx.c Only i386 and amd64 provide a non-trivial __getcontextx(). Use a common trivial implementation in gen/ for other architectures, rather than copying the file to each MD subdirectory.
