Summary: This patch adds assembly-level support for a new Arm M-profile architecture extension, Custom Datapath Extension (CDE). A brief description of the extension is available at https://developer.arm.com/architectures/instruction-sets/custom-instructions The latest specification for CDE is currently a beta release and is available at https://static.docs.arm.com/ddi0607/aa/DDI0607A_a_armv8m_arm_supplement_cde.pdf CDE allows chip vendors to add custom CPU instructions. The CDE instructions re-use the same encoding space as existing coprocessor instructions (such as MRC, MCR, CDP etc.). Each coprocessor in range cp0-cp7 can be configured as either general purpose (GCP) or custom datapath (CDEv1). This configuration is defined by the CPU vendor and is provided to LLVM using 8 subtarget features: cdecp0 ... cdecp7. The semantics of CDE instructions are implementation-defined, but the instructions are guaranteed to be pure (that is, they are stateless, they do not access memory or any registers except their explicit inputs/outputs). CDE requires the CPU to support at least Armv8.0-M mainline architecture. CDE includes 3 sets of instructions: * Instructions that operate on general purpose registers and NZCV flags * Instructions that operate on the S or D register file (require either FP or MVE extension) * Instructions that operate on the Q register file, require MVE The user-facing names that can be specified on the command line are the same as the 8 subtarget feature names. For example: $ clang -target arm-none-none-eabi -march=armv8m.main+cdecp0+cdecp3 tells the compiler that the coprocessors 0 and 3 are configured as CDEv1 and the remaining coprocessors are configured as GCP (which is the default).
