The loop in the following example contains a lexically forward loop-carried dependency that prohibits concurrent execution of all iterations of the loop. Theomp simd safelen(4)directive specifies that the loop iterations that are at a distance of four or less in the logical iteration space can b...
You can take advantage of theomp for simddirective by nesting it inside theomp parallelconstruct or using the combined constructomp parallel for simd. Examples int N = 8; int a[N]; #pragma omp target map(to: N) map(tofrom: a) #pragma omp parallel for simd for (i=0, i<N, i++)...

I would also like to see a test for #pragma omp declare simd that is at the end of the TU with no futher statements (to ensure it gets diagnosed). Ok, will be added. Copy paste error? Nope, I have to verify that the compiler allows to mark the same ...
