--- Comment #5 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Somewhat related: In terms of OpenMP (to be refined in the spec), the following
applies (in order to work both with shared + nonshared memory):
int x = 5;
#pragma omp target map(from:x)
x = 7;
printf("%f\n", x);
This code is invalid – which means that the compiler could use this for
optimization and it probably should warn that "x" is used uninitialized.
