> Not sure what exactly happened

It went like this:

0. Patch set 2 is uploaded.
1. Both clang and virl jobs (among others) are triggered.
2. Both jobs fail (virl on the usual NFS mount symptom).
3. Virl job has naginator, so its result is reported as NOT_BUILT.
4. Clang is reported as FAILURE, so vote is -1.
5. Naginator triggers another run of virl job (only).
6. This time virl job is SUCCESS.
7. Jenkins sees no falure in all 1 job from latest trigger, so votes +1.

I am not sure we can explain Jenkins that
results from previous trigger rounds still aply (if not superseded).

I recommend to disable naginator on the virl job
and rely on methods which trigger all verify jobs.

Version 1 of the same patch failed properly, for the same error message, then I 
removed
permute inline functions and left blend as i missed that same error happens 
also for blend.

Not sure what exactly happened, but it doesn't look like it is not configured 
for voting as it worked properly for PatchSet 1 ...

Reason why this is failing on clang is that clang guys use 
__builtin_shufflevector for multiple
intel intrinsics, and that builtin insist on immediate value for some 
parameters, and it refuses to use
inline function argument, even if that argument is constant.

I will need to redo this with __asm__ ()....

Hi Dave & allm

Sorry about that,I actually merged the patch. However, it was indeed Verified+1 
:(

I have gone now to see the actual CLANG build failure and wondering: is it 
possible that job is not configured as voting/gating job in Jenkins so the 
verification process succeeds anyway?

Importance: High

Folks,

Unfortunately, the AVX2 blend patch causes 100% clang validation failures on 
unrelated patches. The clang validation job actually failed on the original 
patch, but somehow fd.io<http://fd.io/> JJB voted +1 anyhow.

See https://gerrit.fd.io/r/#/c/13457 – revert, https://gerrit.fd.io/r/#/c/13408 
- original patch.

Thanks... Dave
