# Note that asan doesn't work with binaries that use the GPU, so this is
# only useful for tools like triton-opt that don't run code on the GPU.

# I tried and gave up getting msan to work. It seems that libstdc++'s
# std::string does not play nicely with clang's msan (I didn't try
# gcc's). I was unable to configure clang to ignore the error, and I
# also wasn't able to get libc++ to work, but that doesn't mean it's
# impossible. :)
