A list of blacklists for tsan instrumentation. One hopes more can be removed over time as tsan improves. The path needs to be absolute so it doesn't break when directories change during the build: ./configure --with-coroutine=gthread --disable-pie \ --extra-cflags="-g3 -O0 -fsanitize=thread \ -fsanitize-blacklist=/home/alex/lsrc/qemu/qemu.git/blacklist.tsan" Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> --- blacklist.tsan | 2 ++ 1 file changed, 2 insertions(+) create mode 100644 blacklist.tsan -- 2.9.3
