Hi Vladimir, sorry for the late reply. I am just back from holiday.

Thanks for the patch. I have tested that it fixes the ICE reported here!

scratch register in reload instructions are replaced by pseudo registers just
as other instructions feeding into LRA.

I have also did regression test and bootstrap check. It's all good for
aarch64-none-linux-gnu toolchain.

Are you going to post it?
