I'm now going to try to compile HIRLAM with 32 bit pointers.
And ... here are the results:
With 64-bit pointers: 2685 out of 9799 loops vectorized.
With 32-bit pointers: 3269 out of 8854 loops vectorized.
Why there are more loops in the 64-bit case is beyond my understanding -
it's the same code base as I worked on with the 32-bit compilation ...
Kind regards,
