// doris_be_test on macOS/arm64 links against the system allocator instead of
// tcmalloc: the Debug test binary's .text exceeds arm64's +/-128MB direct
// branch reach and Apple's linker emits no branch islands for the prebuilt
// gperftools archive. These no-op definitions satisfy the few gperftools
// symbols still referenced unconditionally (HeapAction's HTTP handler, which
// no unit test invokes, and brpc's periodic MallocExtension release hint).
// Everywhere else the real libtcmalloc.a provides them and this TU is empty.
