2297 dnl We need to decide at configure time if GLib will use real atomic
2298 dnl operations ("lock free") or emulated ones with a mutex. This is
2299 dnl because we must put this information in glibconfig.h so we know if
2300 dnl it is safe or not to inline using compiler intrinsics directly from
2301 dnl the header.
2302 dnl
2303 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2304 dnl user is interested in knowing if they can use the atomic ops across
2305 dnl processes.
2306 dnl
2307 dnl We can currently support the atomic ops natively when building GLib
2308 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2309 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2310 dnl we are using GCC (and not mingw*).
2311 dnl
2312 dnl Note that the atomic ops are only available with GCC on x86 when
2313 dnl using -march=i486 or higher. If we detect that the atomic ops are
2314 dnl not available but would be available given the right flags, we want
2315 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2316 dnl that then to silently fall back on emulated atomic ops just because
2317 dnl the user had the wrong build environment.
