# Empty build type, as upstream Darling uses: objc4 always defines OBJC_IS_DEBUG_BUILD=1,
# so Release's -DNDEBUG trips its "mismatch in debug-ness macros" #error.
# x86-64 only: the patched OpenDirectory declares ivars in @implementation, which the
# 32-bit (fragile ABI) slice cannot compile, and the macOS client is 64-bit.
# darling-lol perf: inject -O3 and -march=native even with empty build type,
# so the base Darling runtime is not compiled at -O0.  The empty build type
# is required by objc4's debug-ness macro check.
# -mtune=generic, not native: clang 23 tuning for AMD Zen (znver*) passes the thread-local
# variable descriptor in the wrong register on Darwin targets, so every __thread access
# returns NULL (launchd crashed in libkqueue's epoll_event_dump).
