URL: https://github.com/llvm/llvm-project/commit/5932bf1730629a1c2673cfdd31d5d823e62a33c3 DIFF: https://github.com/llvm/llvm-project/commit/5932bf1730629a1c2673cfdd31d5d823e62a33c3.diff LOG: [clang][AArch64][SVE] Change SVE_VECTOR_OPERATORS macro for VLA vectors The __ARM_FEATURE_SVE_VECTOR_OPERATORS macro should be changed to indicate that this feature is now supported on VLA vectors as well as VLS vectors.
