2282 dnl We need to decide at configure time if GLib will use real atomic
2283 dnl operations ("lock free") or emulated ones with a mutex. This is
2284 dnl because we must put this information in glibconfig.h so we know if
2285 dnl it is safe or not to inline using compiler intrinsics directly from
2286 dnl the header.
2287 dnl
2288 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2289 dnl user is interested in knowing if they can use the atomic ops across
2290 dnl processes.
2291 dnl
2292 dnl We can currently support the atomic ops natively when building GLib
2293 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2294 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2295 dnl we are using GCC (and not mingw*).
2296 dnl
2297 dnl Note that the atomic ops are only available with GCC on x86 when
2298 dnl using -march=i486 or higher. If we detect that the atomic ops are
2299 dnl not available but would be available given the right flags, we want
2300 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2301 dnl that then to silently fall back on emulated atomic ops just because
2302 dnl the user had the wrong build environment.
