Richard,

Thank you for getting this merged and backported.  Although I initially didn't
observe this problem in gcc 11, I have since confirmed that with the right
flags  (-march=armv8.4-a+sve) it can be exposed as far back as gcc-8.  My
understanding is that versions 11 and 12 should still expect at least one more
release, should those branches receive a backport as well?
