Home > Using the NEON Vectorizing Compiler > Nonvectorization on conditional loop exits |
For vectorization purposes, it is best to write loops that do not contain conditional exits from the loop.
The following example is nonvectorizable because it contains a conditional exit from the loop. In cases like this, you must rewrite the loop, if possible, for vectorization to succeed.
int a[99], b[99], c[99], i, n; ... for (i = 0; i < n; i++) { a[i] = b[i] + c[i]; if (a[i] > 5) break; };
