See https://bugs.llvm.org/show_bug.cgi?id=35243.

Some of the __aeabi_mem* functions in src/arm.rs probably can't be written in Rust because they have special ABI requirements.

We should wait and see what the resolution of LLVM ticket is.

We could just write them directly in assembly. I did that recently, it wasn't bad at all.
