Thanks for letting me know that this is in the works. This is something that would make running ASan (and all other sanitizers I assume) quite a bit more appealing on Android. If there's anything I can do to help, please let me know. If you'd like to discuss in person, I'll be at the Developers' Meeting next week. -Greg On Thu, Oct 31, 2013 at 1:58 PM, Alexey Samsonov

I am trying to run NFS-Ganesha with ASAN in our setup. I am having difficulties to make llvm symbolizer print symbol names from the .debug binaries/libraries, once ASAN shows any error; bash-4.2# /opt/rh/llvm-toolset-7/root/usr/bin/llvm-symbolizer --version LLVM (http://llvm.org/): LLVM version 5.0.1 Optimized build. Default target: x86_64-unknown-linux-gnu Host CPU: nocona I am getting

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

# Summary Currently the Sanitizer family of runtime bug finding tools (e.g. Address Sanitizer) provide useful reports of problems upon detection. This RFC proposes adding tools to 1. Parse Sanitizer reports into structured data to make interfacing with other tools simpler. 2. Take the Sanitizer reports and “Symbolicate” them. That is, add missing symbol information (function name, source file,

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'm having problems building llvm-gcc for Ada, which may or may not be similar to the trouble Andre was having recently. I'm trying to build it on Fedora 10 (32-bit), using the instructions on the web site. The make terminates with a gnatbind error: gcc -c -g -O2 -gnatpg -gnata -I- -I. -Iada -I../../llvm-gcc-4.2/gcc/ada ../../llvm-gcc-4.2/gcc/ada/gnat1drv.adb -o ada/gnat1drv.o

The sanitizer common and asan that mention 'thread' are failing for me this morning. How are your bots looking?

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

Hi, AFAIK, the tools "symbolizer, objdump and nm" need a demangler. I see there is libcxxabi which provides the demangle library. But there is no support to build libcxxabi on windows with MSVC. This left a huge void and my symbolizer cannot work on Windows if built with MSVC. Instead of mucking around OS dependencies, why shouldn't we have a demangle library in LLVM.

Hi Nick, Bigcheese, When lld is used to link C++ code, it would be required to demangle symbol names by default/user driven option. The Gnu linker has the following options :- --demangle=[style] --no-demangle I found that clang/llvm-symbolizer use __cxx_demangle function. I would think that lld also need to call the same function, and I think the way we want to demangle is to have the

Hello! We want to implement in-process symbolizer for {Address,Thread}Sanitizer testing tools that would be based on LLVM libraries. I've noticed that llvm-nm (as well as other tools) doesn't demangle C++ names. Is it true, that LLVM doesn't have the code that is capable of that, and if yes, are there any plans to add it? Depending on something like libiberty.a doesn't seem like a

In the same way that llvm does not depend on clang, compiler-rt

Hi there Firstly I must claim that this is the first time I using a mailing list and I am not familiar with the rules here. As well I am not so good at English too. So here's my apologizes if I'm not able to claim the problem clearly. I'm now using CentOS 6.3 with kernel 2.6.32-279.19.1.el668. Recently I wanna transfer my work from WIndows 8 to Linux.
