My last commit I tested on aarch64 but vect_long_mult was not actually invoked
and I didn't notice that I was missing a `[` in front of
check_effective_target_aarch64_sve.
When I ran the testsuite on x86_64, I got the failure.
Committed as obvious after testing on x86_64.

Yes, it is for a use case inside of rustc_codegen_gcc.

Ping! That's a one-line fix, and you can find all the details in the
bugzilla entry. Also, I can provide executables built with the affected

We can't support niters with may_be_zero when we end up with a
non-empty latch due to early exit peeling. At least not in
the simplistic way the vectorizer handles this now. Disallow
it again for exits that are not the last one.

Hi,
on Solaris/SPARC several vector tests appeared to be regressing. They
were never vectorized but the checks before r14-3612-ge40edf64995769
would match regardless if a loop was actually vectorized or not.
The refined checks only match a successful vectorization attempt
but are run unconditiona

This is enough to get gfx1100 working for most purposes, on top of the
patch that Tobias committed a week or so ago; there are still some test
failures to investigate, and probably some tuning to do.
It might also get gfx1030 working too. @Richi, could you test it,
please?
I can't test the other

Thank you for your help. I will update the test case.
I test on the Coremark and have 5% improvement on the SiFive CPU.
