Umm... this works on x86. What's the problem on ARM? I'll investigate now that I'm back.

Looks like LLVM casts pointers to integers on 32-bit archs when loading, so I might need to implement the interconversion between range <-> nonnull there too.

status:

I have a patch that makes this work on 32-bit archs, now I just need to make it publication-ready and get in touch with @chandlerc.

However, maybe I should just land this change now, ignoring 32-bit archs?

Ignoring seems fine to me

[LLVM] Avoid losing the !nonnull attribute in SROA
ecf62e4 
This still does not work on 32-bit archs because of an LLVM limitation,
but this is only an optimization, so let's push it on 64-bit only for now.

Fixes rust-lang#37945
