2157 dnl We need to decide at configure time if GLib will use real atomic
2158 dnl operations ("lock free") or emulated ones with a mutex. This is
2159 dnl because we must put this information in glibconfig.h so we know if
2160 dnl it is safe or not to inline using compiler intrinsics directly from
2163 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2164 dnl user is interested in knowing if they can use the atomic ops across
2167 dnl We can currently support the atomic ops natively when building GLib
2168 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2169 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2170 dnl we are using GCC (and not mingw*).
2172 dnl Note that the atomic ops are only available with GCC on x86 when
2173 dnl using -march=i486 or higher. If we detect that the atomic ops are
2174 dnl not available but would be available given the right flags, we want
2175 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2176 dnl that then to silently fall back on emulated atomic ops just because
2177 dnl the user had the wrong build environment.
