...ctions can be tested in isolation. > our bots seem to be green. Could you refer to guilty svn revision? Hmm, I just did another clean build, just to be sure. I consistently have see 14 failures (tests and logs below). I believe r182853 broke the SanitizerCommon tests and r182854 broke the asan tests, but I'm not 100% certain and unfortunately don't have time to dive into this one. Would you mind taking a quick scan of the logs below and letting me know if anything stands out to you. Failing Tests (14): AddressSanitizer :: Linux/unpoison_tls.cc AddressSanitizer :: deep_t...

...yte 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 should add the flag anyways, possibly replacing the latter, please let me know. - I've modified the build so that we always run the ASan instrumentation test suite for shadow scale values of 3 and 5. - I've gone through the asan test suites to make...

I have ported ASan in LLVM to Myriad RTEMS, and I would like to upstream the port. Below is the design doc. Feedback welcome. https://docs.google.com/document/d/1oxmk0xUojybDaQDAuTEVpHVMi5xQX74cJPyMJbaSaRM The port is expected to work with modified versions of RTEMS and newlib. I have a git repo with changes to...

...me/libprofile/LLVM.build/Debug/profile_rt-static.build/Objects-normal/x86_64; the second a libtool failure… both went away upon a rebuild.) Third, a build of the check-all target produced 8 warnings about the 8 functions declared noreturn as for ALL_BUILD, and 6 or 7 "errors", mostly from asan_mac_test.mm. After fixing up these "errors" (int vs. size_t comparisons and malloc being assigned to volatile pointers), I got 372 duplicate symbol errors from this: Ld /Volumes/Shared/NewShared/llvm/3.2/xcode/projects/compiler-rt/lib/asan/tests/Debug/AsanTest normal x86_64 cd /Volum...

Those look like the linker is being passed the same .o file built twice, ex: ../Objects-normal/x86_64/asan_globals_test.o ../lib/asan/tests/asan_globals_test.cc.asan.o So, the symbols are colliding.

Why does compiler-rt ship a shared object for ASan on Android instead of a static library? Would statically linking ASan on Android at least be safe for standalone executables? And if I'm wanting to use ASan in C++ code that is invoked from an APK, can I statically link ASan? If not, what is the reason we need to preload Dalvik with the ASan...

Hi Duncan, I came across something like the following recently which I guess might be related to your recent work. Any ideas? $ clang++-tot -cc1 crash_on_invalid.cpp -g -emit-obj -fexceptions -fcxx-exceptions crash_on_invalid.cpp:13:1: error: C++ requires a type specifier for all declarations x; ^ 1 error generated. *** Error in `clang++-tot': corrupted double-linked list: 0x000000000754f340

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...

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 with...
