Author: andrew Date: Tue Dec 18 07:26:55 2012 New Revision: 244382 URL: http://svnweb.freebsd.org/changeset/base/244382 Log: Get libcompiler-rt and libgcc building on ARM with clang. * Don't provide clear_cache or the __sync_* functions on ARM with clang as they are provided by clang as builtin functions. * Tell clang it is aloud to compile some libgcc code using heinous GCC extensions.
