LGTM, but with a nit, I don't get set.w but get an andi like below, so
maybe we should also scan-assembler-not andi? feel free to commit that

Interesting. I can do that, but can you please share the compilation
options, given or defaulted (from `--with...' configuration options), this
happens with?
I have noticed it went nowhere. Can you please check what compilation
options lead to this discrepancy so that we can have the fix included in
GCC 13? I'd like to understand what's going on here.
FWIW, I don't see the redundant sign extension with this testcase at -O2
on the trunk. Is it possible the patch has been made redundant over the
last few months?
