rationale: |
A Full Software Memory Barrier prevents the compiler to move loads and
stores (in any direction) beyond the point where the barrier is in the
code. Otherwise this may occur as part of compiler optimizations.
This is a compile time only barrier. The CPU optimizations can still
move instructions over the barrier at run-time.

When the code is compiled with the GNU C compiler,
the ${../if/compiler-memory-barrier:/name} macro shall
realize a Full Software Memory Barrier at the place in the code where
it occurs.
