2329 dnl operations ("lock free") or emulated ones with a mutex. This is
2330 dnl because we must put this information in glibconfig.h so we know if
2331 dnl it is safe or not to inline using compiler intrinsics directly from
2334 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2335 dnl user is interested in knowing if they can use the atomic ops across
2338 dnl We can currently support the atomic ops natively when building GLib
2339 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2340 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2341 dnl we are using GCC.
2343 dnl Note that the atomic ops are only available with GCC on x86 when
2344 dnl using -march=i486 or higher. If we detect that the atomic ops are
2345 dnl not available but would be available given the right flags, we want
2346 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2347 dnl that then to silently fall back on emulated atomic ops just because
