2192 dnl ************************
2194 dnl We need to decide at configure time if GLib will use real atomic
2195 dnl operations ("lock free") or emulated ones with a mutex. This is
2196 dnl because we must put this information in glibconfig.h so we know if
2197 dnl it is safe or not to inline using compiler intrinsics directly from
2198 dnl the header.
2199 dnl
2200 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2201 dnl user is interested in knowing if they can use the atomic ops across
2202 dnl processes.
2203 dnl
2204 dnl We can currently support the atomic ops natively when building GLib
2205 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2206 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2207 dnl we are using GCC (and not mingw*).
2208 dnl
2209 dnl Note that the atomic ops are only available with GCC on x86 when
2210 dnl using -march=i486 or higher. If we detect that the atomic ops are
2211 dnl not available but would be available given the right flags, we want
2212 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2213 dnl that then to silently fall back on emulated atomic ops just because
2214 dnl the user had the wrong build environment.
2216 dnl We may add other compilers here in the future...
