Hello , I thought about MSAN memory sanitizer and OpenJDK. See https://clang.llvm.org/docs/MemorySanitizer.html https://github.com/google/sanitizers/wiki/MemorySanitizer
We have already some sanitizer support in OpenJDK e.g. for ASAN (address) and UBSAN (undefined behavior). Would MSAN be still useful , or is everything already covered by other tools? Was there already some attempt to try out/support MSAN with OpenJDK ? While looking into it, it seems that so far MSAN only works with clang (while e.g. UBSAN works with clang and gcc), is that correct ? Btw. while giving it a try to compile OpenJDK with MSAN support (Linux/clang ; added build flags -fsanitize=memory -fno-omit-frame-pointer ) I was running into this …/jdk/bin/javac: symbol lookup error: …/jdk/bin/../lib/libjli.so: undefined symbol: __msan_param_tls (maybe someone has seen a similar error ?) Best regards, Matthias
