\ Well dang. I can't reproduce with sparc64 gcc-15.2.0. Documentation/process/changes.rst says we support 8,1, released in 2018. Your 8.5 was released in 2021 so perhaps three other people are still using it :( https://www.kernel.org/pub/tools/crosstool/ doesn't appear to have sparc64 gcc-8.5 so I gave up. So I dunno. I'm inclined to ignore and assume that if someone else hits this one day, they'll either fix it or provide us with enough details to figure it out.
