Now compiler-rt has been updated in r276851, bring in the various sanitizer libraries that already work on FreeBSD: * asan: Address Sanitizer * ubsan: Undefined Behavior Sanitizer * profile: Profile Guided Optimization support Please note that these libraries are experimental at this stage, so the main Makefile is not yet connected to the build. Since I didn't want to needlessly edit BSD.usr.dist, you will also have to create the install directory /usr/lib/clang/3.5.0/lib/freebsd manually for now. 2015-01-08 22:40:56 +00:00			`# $FreeBSD$`

Connect libclang_rt to the build, for specific architectures. This contains the libraries for Address Sanitizer (asan), Undefined Behavior Sanitizer (ubsan) and Profile Guided Optimization. ASan is a fast memory error detector. It can detect the following types of bugs: Out-of-bounds accesses to heap, stack and globals Use-after-free Use-after-return (to some extent) Double-free, invalid free Memory leaks (experimental) Typical slowdown introduced by AddressSanitizer is 2x. UBSan is a fast and compatible undefined behavior checker. It enables a number of undefined behavior checks that have small runtime cost and no impact on address space layout or ABI. PLEASE NOTE: the sanitizers still have some rough edges on FreeBSD, particularly on i386. These will hopefully be smoothed out in the coming time.
