...t functionality, we could use that instead. This is my first code in LLVM, so it definitely needs cleanup to meet the LLVM guidelines. Run time library (could be used with any other compiler): - Almost everything is on one file: http://code.google.com/p/address-sanitizer/source/browse/trunk/asan/asan_rtl.cc This library replaces malloc, tracks thread stacks, replaces SIGILL and SIGSEGV handlers, reports warnings. Linux x86/x86_64 and ChromiumOS is fully functional, MacOS is in flight. Tests: http://code.google.com/p/address-sanitizer/source/browse/trunk/asan/asan_test.cc --kcc > -Chris >...

...LLVM trunk? The instrumentation pass is ~350 LOC ( http://code.google.com/p/address-sanitizer/source/browse/trunk/llvm/AddressSanitizer.cpp), but may grow over time as we add optimizations. The run-time library (malloc replacement, http://code.google.com/p/address-sanitizer/source/browse/trunk/asan/asan_rtl.cc) is ~1500 LOC.

Indeed, removing that flag works fine, the only question is why this is added in tools/llvm-shlib/Makefile in the first place then and what to do about it: ifeq ($(HOST_OS), $(filter $(HOST_OS), Linux GNU GNU/kFreeBSD)) # Don't allow unresolved symbols.
