Hi Martin,
Thanks for opened eyes, following patch will fix that.
It's quite obvious, I'll install it right after tests will finish.
unfortunately, it didn't fix either issue:
* The switchlower -> switchlower1 renames in the dg-final* lines
(attached) are still necessary to avoid the UNRESOLVED errors.
Although obvious, I haven't installed them since ...

You are right, it's using -O2, thus your patch is right. Please install the
patch
after testing. It's obvious fix.
But what about the remaining FAIL?
Sorry to add to this, but I have also observed the following failures on aarch64-none-elf, aarch64-none-linux-gnu and aarch64_be-none-elf targets bisected to this commit:
