<pre>Hi Loris,
Thanks for reporting the issue.
The error message "Running pass 'X86 ..." indicates that that llc is doing
instruction selection for x86. Scalable vectors are only supported with
-mtriple=aarch64 and -mattr=+sve (or equivalent function attributes).
Your reproducer produces correct code when fed into llc -mtriple=aarch64
-mattr=+sve: <a href="https://godbolt.org/z/Tb7ajPx3T">https://godbolt.org/z/Tb7ajPx3T</a>
I'm marking this as resolved but please reopen the thread if I've missed
something, and please file another bug if you find this kind of error through
another route.
Regards,
- Peter</pre>
