Author: dim Date: Tue Mar 24 22:39:18 2015 New Revision: 280474 URL: https://svnweb.freebsd.org/changeset/base/280474 Log: Pull in r231002 from upstream llvm trunk (by Rui Ueyama: Support: Add {read,write}{16,32,64}{le,be} functions. Add convenient functions for endian-aware reads/writes. This is a prerequisite for building lld trunk.
