Sorry for my first misleading email. The code needs disabled
optimizations to ensure that the execution time is long enough
to measure jitter. It has nothing to do with the correctness of the
C code. It might be still an issue, to depend on an optimization level.
"To ensure that optimizations are
There is some recent code added to Linux 4.2, that relies on disabled
optimization.
This might be an interesting case of unclear interpretation/misuse of
the C language.
#ifdef __OPTIMIZE__
#error "The CPU Jitter random number generator must not be compiled
with optimizations.
See documentation.
