...t the wrong mail listing, but compiler-rt page tells I'd better write on llvm-dev rather than cfe-dev/cfe-users.) I've just built LLVM/Clang+Compiler-rt (Compiler-rt is put inside llvm/projects folder) and tried the -fsanitize option. But strangely the link failed since it cannot find *libclang_rt.san-x86_64.a*.

...ng the MacPorts llvm-3.4 port from the configure-based build system to the cmake-based build system.

Hi all, I want to do fuzzing test on Intel x86_64 platform, however I cannot find the shared library for libclang_rt.asan-x86_64-android.so, can anyone tell me where I can find this library?

[/on topic] Making the emutls objects in libclang_rt visible to libcxxabi.dylib at runtime has been a hiccup, tho. It works but seems a shame to hack emutls.c into the libc++abi code when the objects are already sitting there in the executable, but (AFAICT) have the wrong visibility setting to allow use.

It has come up when reviewing Kostya's patch to add the necessary support fort linking in the Address Sanitizer runtime library that we need a proper scheme and plan for deploying runtime libraries along with Clang. I've CC'ed llvmdev on this for compiler-rt developers' input. The key issues I see when locating runtime libraries are the following: - These libraries should be

So, is there an agreement now? In particular, is it fine to have the asan run-time for linux x86/x86_64 at lib/clang/linux/TC.getArchName())/libclang_rt.asan.a ?

I just tried building the latest clang following the instructions in http://clang.llvm.org/get_started.html, and got this error when trying to compile at test program: /usr/bin/ld: cannot find /home/davem/clang-235334/bin/../lib/clang/3.7.0/lib/linux/libclang_rt.asan-x86_64.a: No such file or directory This thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-April/084175.html indicates that the solution is to start with a clean build, but that's what I just tried, and it still failed.

...is available. (In MacPorts, this is done using -stdlib=macports-libstdc++, which links against a new version of libgcc from gcc8). I would like to enable this while using libc++ as well, however. To do this, libc++abi is built with cxa_thread_atexit.cpp added, and emutls.c is built and used in libclang_rt.10.4.a. However I am having an issue wherein the symbol ___emutls_get_address from lilbclang_rt_10.4.a is not visible to libc++abi.dylib at runtime.
