...is is an improvement.
The patch that added the warning as-is was by me
(https://reviews.llvm.org/D55288). It changed to emitted message from
"loop not vectorized: failed explicitly specified loop vectorization"
to the lengthier description following review feedback.
It's done by the WarnMissedTransformation and just looks for
transformation metadata that is still in the IR after all passes that
should have transformed them have ran. That is, it does not know why
it is still there -- it could be because the LoopVectorize pass is not
even in the pipeline -- and we cannot be more specific in the message....

Hi Michael and Florian,
( + llvm-dev for visibility)
I would like to quickly follow up on "Pragma vectorize_width() implies vectorize(enable)",
which got reverted with commit 858a1ae for 2 reasons, see also that revert commit message. Ignore the assert, that's been fixed now.
The other thing is that with the patch behaviour is slightly changed and we could get a diagnostic we
