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