You can use something like this:

#ifndef __has_feature
#define __has_feature(x)        0
#endif

#if __has_feature(address_sanitizer) || \
    defined(__SANITIZE_ADDRESS__) || \
    __has_feature(leak_sanitizer) || \
    defined(__SANITIZE_LEAK__)

asan_lsan_code_here();

#else

no_asan_lsan_code_here();

#endif


__SANITIZE_LEAK__ is a NetBSD GCC extension.
