Hello, I'm trying to build XNU with KASAN support. However I get error: clang: error: unsupported option '-fsanitize=kernel-hwaddress' for target 'arm64e-apple-darwin23.2.0' If I try to compile a non-kernel C code with -fsanitize=hwaddress, I get the same target error. But Apple ships HWASan kernels with KDK, which shows there is a clang which is capable of compiling hwasan code for arm64e. How can we compile hwasan sanitized code ourselves? Is it a private toolchain or released somewhere?
