For speculation-hardening-sls.ll: the approach taken in the ARM backend version of the similar test is probably a lot more robust, and I'd guess that if the test was adapted to follow the approach there ( see https://github.com/llvm/llvm-project/blob/566690b067c8175314fa657b899c99bccf96821c/llvm/test/CodeGen/ARM/speculation-hardening-sls.ll#L343), the compiler would still use the x16 register.
