# This option enables -fsanitize=hwaddress for stage2 and stage3.
# We need to disable random frame tags for bootstrap since the autoconf check
# for which direction the stack is growing has UB that a random frame tag
# breaks. Running with a random frame tag gives approx. 50% chance of
# bootstrap comparison diff in libiberty/alloca.c.
