This looks like it's a somewhat different problem.

In my case this is what bites me: https://godbolt.org/z/x9bWjePGY
It's a variant of this issue: https://github.com/llvm/llvm-project/issues/51734

I have a WIP patch that converts a GEP with a dynamic index with a known range of values into a series of comparisons and fixed-index GEPs. I guess I'll need to get it sorted out first.
