note: not vectorized: vectorization may not beprofitable.
This is due to switching on vector cost model by default for x86.
Ah, but my hidden critique of the message was:
-ftree-vectorizer-verbose=2 should *only* tell us:
1. Which loops are vectorized.
2. Which are not - and why (in a single sentence).
For more detailed logging, one should use -ftree-vectorizer-verbose=n
with n>2, IMNSHO.
Kind regards,
