[llvm-dev] How do I run llvm's asan tests? (original) (raw)

Your steps seem to be correct....

I've just done this, and it worked fine:

git clone https://github.com/llvm/llvm-project.git cd llvm-project mkdir build cd build cmake -G Ninja -DLLVM_ENABLE_PROJECTS='clang;compiler-rt;' ../llvm ninja check-asan

My gcc is "gcc (Debian 7.3.0-5) 7.3.0"

No good ideas what's broken on your side...

--kcc

Hi llvm-dev, I'm trying to figure out how to contribute to LLVM, in particular a followup to kcc's commit 6bde702a in sanitzersuppressions.cc. However I can't find a way to get the tests to run before I even change anything. The relevant unit test is compiler-rt/lib/sanitizercommon/tests/sanitizersuppressionstest.cc, so I expect I want ninja check-asan (right?). Here's what I tried, on my Debian machine, following (and adjusting) the outdated llvm documentation about setting up a GCC toolchain: # Install the GCC toolchain. # See http://llvm.org/docs/GettingStarted.html#getting-a-modern-host-c-toolchain # Adjusted for GCC 7.4.0, which doesn't ship in a bzip2 archive. gccversion=7.4.0 wget https://ftp.gnu.org/gnu/gcc/gcc-${gccversion}/gcc-${gccversion}.tar.gz wget https://ftp.gnu.org/gnu/gcc/gcc-${gccversion}/gcc-${gccversion}.tar.gz.sig wget https://ftp.gnu.org/gnu/gnu-keyring.gpg signatureinvalid=gpg --verify --no-default-keyring --keyring_ _./gnu-keyring.gpg gcc-${gccversion}.tar.gz.sig if [ $signatureinvalid ]; then echo "Invalid signature" ; exit 1 ; fi tar -xvzf gcc-${gccversion}.tar.gz cd gcc-${gccversion} ./contrib/downloadprerequisites cd .. mkdir gcc-${gccversion}-build cd gcc-${gccversion}-build mkdir -p $HOME/toolchains $PWD/../gcc-${gccversion}/configure --prefix=$HOME/toolchains --enable-languages=c,c++ make -j$(nproc) make install # Clone llvm and try to test it. mkdir -p ~/clients cd ~/clients git clone https://github.com/llvm/llvm-project.git # Get a coffee cd llvm-project mkdir build cd build _CC=$HOME/toolchains/bin/gcc CXX=$HOME/toolchains/bin/g++ _ cmake -G Ninja -DCMAKECXXLINKFLAGS="-Wl,-rpath,$HOME/toolchains/lib64 -L$HOME/toolchains/lib64" -DLLVMENABLEPROJECTS='clang;compiler-rt;libcxx;libcxxabi' ../llvm ninja check-asan # Get another coffee After about 30 minutes, the ninja command fails with an error about how the string header isn't found: FAILED: projects/compiler-rt/lib/asan/tests/ASANNOINSTTESTOBJECTS.asannoinsttest.cc.x8664-inline.o cd /usr/local/google/home/jacobsa/clients/llvm-project/build/projects/compiler-rt/lib/asan/tests && /usr/local/google/home/jacobsa/clients/llvm-project/build/./bin/clang -fPIC -fvisibility-inlines-hidden -Werror=date-time -std=c++11 -Wall -Wextra -Wno-unused-parameter -Wwrite-strings -Wcast-qual -Wno-missing-field-initializers -pedantic -Wno-long-long -Wimplicit-fallthrough -Wno-maybe-uninitialized -Wno-noexcept-type -Wdelete-non-virtual-dtor -Wno-comment -fdiagnostics-color -Wall -std=c++11 -Wno-unused-parameter -Wno-unknown-warning-option -DGTESTNOLLVMRAWOSTREAM=1 -DGTESTHASRTTI=0 -I/usr/local/google/home/jacobsa/clients/llvm-project/llvm/utils/unittest/googletest/include -I/usr/local/google/home/jacobsa/clients/llvm-project/llvm/utils/unittest/googletest -I/usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/include -I/usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/lib -I/usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/lib/asan -I/usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/lib/sanitizercommon/tests -fno-rtti -O2 -Wno-format -Werror=sign-compare -Wno-non-virtual-dtor -Wno-variadic-macros -gline-tables-only -DASANHASBLACKLIST=1 -DASANHASEXCEPTIONS=1 -DASANUAR=0 -m64 -c -o ASANNOINSTTESTOBJECTS.asannoinsttest.cc.x8664-inline.o /usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/lib/asan/tests/asannoinsttest.cc In file included from /usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/lib/asan/tests/asannoinsttest.cc:17: In file included from /usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/lib/asan/tests/asantestutils.h🔞 /usr/local/google/home/jacobsa/clients/llvm-project/compiler-rt/lib/asan/tests/asantestconfig.h:19:10: fatal error: 'string' file not found #include ^~~~~~~~ 1 error generated. This doesn't happen for ninja check-all (but despite its name that target doesn't seem to run the test), so I wonder if it's a hermeticism issue in the asan tests? It's also very possible I've just done it wrong. Help? Thanks, Aaron
