There was also the patch that had them as .insn in the other series of emails.

Sorry, It was in the discussion for v4 patches, as an attachment . mail thread: [PATCH v4 10/11] tests/tcg/s390x: Tests for Vector Enhancements Facility 2 So it likely never made it to the mailing list. I've reattached and will forward the patch (by itself) to the mailing list. I think the other solution works just as well by ignoring if compiler doesn't support z15. I just thought I'd bring it back up as I saw discussion about it.

Ok, I now gave this a try ... and while this should now work fine with older
versions of gcc/binutils, it's failing with Clang now:

Thus I think I'll rather go with the other approach instead that checks for
the availability of -march=z15.

It looks like google killed allowing password access early, nothing makes it work anymore. They had plans to disable 'less secure app' in may, but it thought it was the end of the month. I'll try copy/paste as plain text as well though I Know it will likely screw it up..

Yup, that plain text patch didn't apply anymore - so I went for the attachment from your previous mail this time instead (hoping that you'll find another way for using git-send-email again in the future).
