Comment #4 on issue 345 by [email protected]: Use Linux
madvise(MADV_DONTDUMP) to exclude ASan shadow regions from core dumps
https://code.google.com/p/address-sanitizer/issues/detail?id=345
makes sense. Please send a patch to llvm-commits@ (see
https://code.google.com/p/address-sanitizer/wiki/HowToContribute)
Note that we do not #include system headers in asan_rtl.cc.
You will need to create a separate function similar to
FlushUnneededShadowMemory in
lib/sanitizer_common/sanitizer_posix_libcdep.cc
The change will also need a tests in test/asan/TestCases/Linux
Thanks for the detailed explanation!
