--- Comment #1 from Hongtao Liu <liuhongt at gcc dot gnu.org> ---
For convert3, we already have a patch for it, and will post soon.
For convert, the current loop vectorizer has a limitation to keep the same
vector length while vectorizing, thus generating extra packing/unpacking
instructions compared to convert2. But there's no such limitation in BB
vectorizer, so w/ -O3 -march=x86-64-v3 -fno-tree-loop-vectorize, convert is as
good as convert2
