…r the assembly disassembly This NFC patch refactors the assembly/disassembly class and multiclass in the AArch64 backend to receive a new 2023/09 AArch64[1] ISA release. The encoding for the 2023 instructions re-uses encoding blocks from previous assembly/disassembly instructions. The refactoring makes the class and multiclass for assembly/disassembly generic so it can be used to describe the instructions for the new ISA.
