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.
