2202 dnl ************************
2204 dnl We need to decide at configure time if GLib will use real atomic
2205 dnl operations ("lock free") or emulated ones with a mutex. This is
2206 dnl because we must put this information in glibconfig.h so we know if
2207 dnl it is safe or not to inline using compiler intrinsics directly from
2208 dnl the header.
2209 dnl
2210 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2211 dnl user is interested in knowing if they can use the atomic ops across
2212 dnl processes.
2213 dnl
2214 dnl We can currently support the atomic ops natively when building GLib
2215 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2216 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2217 dnl we are using GCC (and not mingw*).
2218 dnl
2219 dnl Note that the atomic ops are only available with GCC on x86 when
2220 dnl using -march=i486 or higher. If we detect that the atomic ops are
2221 dnl not available but would be available given the right flags, we want
2222 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2223 dnl that then to silently fall back on emulated atomic ops just because
2224 dnl the user had the wrong build environment.
2226 dnl We may add other compilers here in the future...
