I wonder why Andrew S didn't see them (unless he did?). However, I did get a
similar/the same ICE for the testcase in PR113645.
I have not checked whether anything below applies to the PR as well or not but
as Andrew P has marked it as duplicate ...

Regarding PR113645: While, I have no real idea about GCC backend handling, the
following SEEMS TO FIX THE ISSUE for the ICE of the testcase with -O3 and
gfx1030 and gfx1100, also known as
possible patch:
