2210 dnl ************************
2212 dnl We need to decide at configure time if GLib will use real atomic
2213 dnl operations ("lock free") or emulated ones with a mutex. This is
2214 dnl because we must put this information in glibconfig.h so we know if
2215 dnl it is safe or not to inline using compiler intrinsics directly from
2216 dnl the header.
2217 dnl
2218 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2219 dnl user is interested in knowing if they can use the atomic ops across
2220 dnl processes.
2221 dnl
2222 dnl We can currently support the atomic ops natively when building GLib
2223 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2224 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2225 dnl we are using GCC (and not mingw*).
2226 dnl
2227 dnl Note that the atomic ops are only available with GCC on x86 when
2228 dnl using -march=i486 or higher. If we detect that the atomic ops are
2229 dnl not available but would be available given the right flags, we want
2230 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2231 dnl that then to silently fall back on emulated atomic ops just because
2232 dnl the user had the wrong build environment.
2234 dnl We may add other compilers here in the future...
