The assembler syntax is different. It has some similarities for a few mnemonics but you cannot compile one into the other (like we could do with the Thumb-2 unified syntax). The register names are different: R0 on 32-bit vs X0 on 64-bit. Even the comment syntax has been changed from "@" to "//" (because of some clashes of the former).
