I'm getting this link failure when running ninja check on Linux. I'm configuring with shared libraries enabled, so I'm not sure why asan is looking for .a archives. $ cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DLLVM_BUILD_TESTS=ON -DCLANG_INCLUDE_DOCS=ON -DBUILD_SHARED_LIBS=ON ../llvm $ ninja check-all FAILED: cd [..]bld/projects/compiler-rt/lib/asan/tests &&

Hello, I am building sanitizers for our different platforms and trying to use it in an example program, but while it seems like ASAN is running it's init functions (see stdout below with ASAN_OPTIONS=verbosity=1) it never catches anything in the program. This is LLVM 8.0.1 btw. I was using this small test case: int main(int argc, char** argv) { int *array = new int[100]; delete []

I have simple standalone ASan examples working on Android, and now I'd like to try using ASan with the Android build system. I'm building the release_33 branch of llvm+clang+compiler-rt with CMake. To test, I'm looking at libjpg, because with just a small change its Android.mk it compiles in a few seconds and without needing any additional dependencies. When I run 'djpeg' on

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

Hello Alex, Thanks for the hint. It was actually not the -O flag that created the problem. But it pointed me in the right direction, when I passed -fno-experimental-new-pass-manager it started to show the error. My guess is that the new pass manager is more aggressive in removing UB?

Got figured out. I needed to use TARGET_LDFLAGS. LOCAL_LDFLAGS seems to be ignored in my clang build. LOCAL_CFLAGS += -fsanitize=address TARGET_LDFLAGS +=-fsanitize=address -target

Indeed, removing that flag works fine, the only question is why this is added in tools/llvm-shlib/Makefile in the first place then and what to do about it: ifeq ($(HOST_OS), $(filter $(HOST_OS), Linux GNU GNU/kFreeBSD)) # Don't allow unresolved symbols.

Hi everyone, (Sorry if I'm asking at 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*. The error message is as

You are citing the "Android platform workflow" section, which is about sanitizing components of the Android system itself. For NDK apps, see "Android NDK workflow" in the same document. You need -eng build because preloading libraries into dalvik vm is not allowed in user builds. JellyBean includes several bugfixes in the dynamic loader that asan needs. Was there any useful

Actually it only link the shlib fine. Linking any executable against it fails: llvm[2]: Linking Release+Asserts executable llvm-lto (without symbols) /home/kfischer/julia/deps/llvm-svn/build_Release+Asserts/Release+Asserts/bin/clang++ -fsanitize=address -O3 -Wl,-R -Wl,'$ORIGIN/../lib' -L/home/kfischer/julia/deps/llvm-svn/build_Release+Asserts+Sanitize/Release+Asserts/lib

I've finished my initial set of patches to make 32-byte shadow granularity work on x86. Here is a summary of the changes from last week: - As discussed, I added a full redzone after every stack variable. - We discussed adding a -fsanitize-address-granularity=N flag, but I found the following existing flag has been sufficient for my purposes: -asan-mapping-scale N. If anyone thinks I

If running ASan on the host architecture, we can symbolize output with: export LLVM_SYMBOLIZER_PATH=`which llvm-symbolizer` ./myInstrumentedProgram but on Android symbolizing is more complex. The bash script below is a "hello world" for symbolizing ASan output on Android. Is there a simpler way to do this? # Execute the test and save its output adb push

Thanks All In fact, to answer Pete, I was trying to do as much as possible like valgrind including as much as possible, which includes all tools. M very elated to know about ASan, given the fact that LLVM is Compile time whereas valgrind is Dynamic, need to rethink, Can you guys check this. build clang 3.2 but I got this linker error. Let me also examine closely clang++ -W -Wall

Hi Kcc, I'm trying enabling the Asan in my firmware, but I find the asan instrumentation code size impact is too big for me. I just implement necessary firmware version runtime library functions (e.g. __asan_report_load8) with blank body firstly to pass the asan enabled build, but I find the new binary code size is already ~2.5 times as original one with asan disabled in GCC. I know Linux

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?
