<pre>The following testcase:
#include <stdio.h>
int main() {
int s[10];
int count = 0;
#pragma omp target if(0)
#pragma omp parallel num_threads(8)
{
#pragma omp for ordered
{
for (int i=0;i<10;i++) {
s[i] = count;
count++;
}
}
}
for (int i=0;i<10;i++) {
printf("%d\n", s[i]);
}
return 1;
}
prints out:
2
4
1
5
6
0
7
4
3
8
on latest clang+openMP from git repositories. Successive re-runs show different
orders.
I would have instead expected an ordered print of numbers from 0 to 9.</pre>
