How do I use the sanitizer coverage option? I am unable to use it with clang-17.
./llvm-project/install/bin/clang -fsanitize=address -fsanitize-coverage-allowlist=allowlist.txt hello.c
clang++: warning: argument unused during compilation: ‘-fsanitize-coverage-allowlist=allowlist.txt’ [-Wunused-command-line-argument]
