+/**
+ * \def MBEDTLS_AESCE_C
+ *
+ * Enable AES crypto extension support on Arm64.
+ *
+ * Module:  library/aesce.c
+ * Caller:  library/aes.c
+ *
+ * Requires: MBEDTLS_HAVE_ASM, MBEDTLS_AES_C
+ *
+ * \note The code uses Neon intrinsics, so \c CFLAGS must be set to a minimum
+ * of \c -march=armv8-a+crypto .
+ *
+ * \warning If the target architecture is set to something that includes the
+ *          SHA3 feature (e.g. `-march=armv8.2-a+sha3`), for example because
+ *          `MBEDTLS_SHA512_USE_A64_CRYPTO_IF_PRESENT` is desired, compilers
+ *          generate code for `MBEDTLS_AESCE_C` that includes instructions
+ *          only present with the (optional) SHA3 feature. This will lead to an
+ *          undefined instruction exception if the code is run on a CPU without
+ *          that feature.
+ *
+ * \warning Runtime detection only works on linux. For non-linux operation
+ *          system, crypto extension MUST be supported by CPU.
+ *
+ * This module adds support for the AES crypto instructions on Arm64
