Hi, I am using clang++3.9 to build a simple program with both CFI and safe-stack. I am getting linker errors when combining -fsanitize=safe-stack, -fsanitize=cfi, and -fno-sanitize-trap=all. Combining safe-stack and CFI without -fno-sanitize-trap=all works as expected. It looks like clang is attempting to link in two compiler-rt libraries, one for ubsan and one for safestack, and this causes

Note that I've set the SA_NODEFER flag for the SEGV handler in the ASan runtime only a couple of days ago. Not sure that could've affected this test though; without that flag the second SEGV would've simply crashed the program. But you can try removing the flag from compiler-rt/trunk/lib/sanitizer_common/sanitizer_posix_libcdep.cc and see if that makes any difference. HTH, Alex On

Hi, I see that ENABLE_WERROR is being set to off (the default value) in the config.log in the llvm build. However on grepping for WERROR in the compiler-rt folder I get the following output: pranav at pranav:~/smack-project/llvm-3.4/src/projects/compiler-rt$ grep -Rin WERROR * lib/asan/tests/CMakeLists.txt:38: -Werror lib/asan/asan_malloc_mac.cc:253:// This function is currently unused, and we

I've been building clang on linux for a couple of years now, contributing to the testing on Ubuntu, but this one has me stumped: fatal error: 'asm/socket.h' file not found #include <asm/socket.h> [1556/4006] Building CXX object projects/compiler-rt/lib/sanitizer_common/CMakeFiles/RTSanitizerCommon.i386.dir/sanitizer_platform_limits_posix.cc.o FAILED:

Dear Alexey, Yes I am sure that the llvm, clang and compiler-rt are synced to the same version. I downloaded them all from git http://llvm.org/docs/GettingStarted.html#git-mirror I think I need compiler-rt for my project but I'll verify it again to see if I can proceed without it. You are correct that compiler-rt is compiled with the just built clang. The complete command that gives an error

Hi, I'm trying to build llvm 3.4 on one of our Cray systems, note: 3.2 builds fine. The following error occurs, it looks like a system header, intended for C only judging by the fact that there's a variable named "new", is being used in one of llvm's C++ source files. Can anyone suggest a workaround? I do not have root on this system nor is it likely that I can convince

yes I think that is correct. I wrote a simple program to print if sizeof(uintptr_t) != sizeof(unsigned char *) and when I compile with gcc -m64 and execute it on a 64-bit host (that is different from the 32-bit laptop on which I originally compiled the program), it says the sizes are not equal.

Hi, It would be great if the spec file could be updated to remove the dependency on python-ctypes for sles 11 since this seems to be included as part of the python package. Also, there are lot of pragma warnings. It doesn't look like those pragma's work with the gcc on suse 11p2: ../../../../rpc/xdr/src/cli1-xdr.h:25: warning: unknown option after '#pragma GCC diagnostic' kind

Hi there, I am sure this question has been posted a couple times before but I could not find a good solution on the web. Is there any way to get png() support in R on SUSE linux? We want to run GenePattern on that server and some workflows use R scripts plotting into pngs.

Hi all, I have been experiencing the failure of the address sanitizer regression tests for a PPC64 target (Power7 machine). My understanding is that most of the failures are related with the fact the stack is not being dumped. I tried to understand what might be wrong and started by looking into the null_deref.cc test as it hangs during the test run. I observe that after the detection of the

Thanks! I'll try that. In order to avoid starting a new thread, let me ask you the next question. One of the shared libraries I load calls strtol and msan fails to intercept it. Why would this be? The library seems to be otherwise implemented. One of the potential culprits I saw is that strtol is marked as strong in libc. Is there any workaround? Keno On Thu, Apr 9, 2015 at 3:00 PM, Evgeniy
