Subject: [ASan] Link with the dynamic runtime on OS X
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f6b56972d50e75ba1bcf4639f5d217aebabc694b;p=platform%2Fupstream%2Fllvm.git

[ASan] Link with the dynamic runtime on OS X
This patch changes the behavior of the -fsanitize=address flag, making it use the dynamic runtime library (libclang_rt.asan_osx_dynamic.dylib) instead of the static one. It also drops the CoreFoundation dependency, since the dynamic runtime doesn't need it.
