I think I asked this before but how does OpenMP handle the C99
equivalent of this?
Like:
void abort ();
int check;
int f1() { check |= 1; return 1; }
int f2() { check |= 2; return 11; }
int f3() { check |= 4; return 2; }
int a[12];
int main()
{
#pragma omp for
for (int i = f1(); i <= f2(); i += f3())
a[i] = 1;
for (int i = 0; i < 12; ++i)
if (a[i] != (i & 1))
abort ();
}
Also while you are hacking this code, it seems like you could fix
the long standing bug in that the i does not declared in the
correct scope so the following C++ code is invalid:
void f(int l)
{
for(int i = 0;i<l;i++)
{
int i = 2;
}
}
