Add in SVE/SVE2/MOPS features for aarch64 cpus. These features may be interesting for future memory/math routines. SVE/SVE2 are now being accepted in more implementations: ``` ❯ echo | clang-21 -dM -E - -march=native | grep -i ARM_FEAT #define __ARM_FEATURE_ATOMICS 1 #define __ARM_FEATURE_BF16 1 #define __ARM_FEATURE_BF16_SCALAR_ARITHMETIC 1 #define __ARM_FEATURE_BF16_VECTOR_ARITHMETIC 1 #define __ARM_FEATURE_BTI 1 #define __ARM_FEATURE_CLZ 1 #define __ARM_FEATURE_COMPLEX 1 #define __ARM_FEATURE_CRC32 1 #define __ARM_FEATURE_DIRECTED_ROUNDING 1 #define __ARM_FEATURE_DIV 1 #define __ARM_FEATURE_DOTPROD 1 #define __ARM_FEATURE_FMA 1 #define __ARM_FEATURE_FP16_SCALAR_ARITHMETIC 1 #define __ARM_FEATURE_FP16_VECTOR_ARITHMETIC 1 #define __ARM_FEATURE_FRINT 1 #define __ARM_FEATURE_IDIV 1 #define __ARM_FEATURE_JCVT 1 #define __ARM_FEATURE_LDREX 0xF #define __ARM_FEATURE_MATMUL_INT8 1 #define __ARM_FEATURE_NUMERIC_MAXMIN 1 #define __ARM_FEATURE_PAUTH 1 #define __ARM_FEATURE_QRDMX 1 #define __ARM_FEATURE_RCPC 1 #define __ARM_FEATURE_SVE 1 #define __ARM_FEATURE_SVE2 1 #define __ARM_FEATURE_SVE_BF16 1 #define __ARM_FEATURE_SVE_MATMUL_INT8 1 #define __ARM_FEATURE_SVE_VECTOR_OPERATORS 2 #define __ARM_FEATURE_UNALIGNED 1 ``` MOPS is another set of extension for string operations, but may not be generally available for now: ``` ❯ echo | clang-21 -dM -E - -march=armv9.2a+mops | grep -i MOPS #define __ARM_FEATURE_MOPS 1 ```
