  "message": "Switch __ARM_FEATURE_CRYPTO to __ARM_FEATURE_{AES,SHA2}.\n\nThe latest version of ACLE splits __ARM_FEATURE_CRYPTO into two defines\nto reflect that, starting ARMv8.2, the cryptography extension can\ninclude {AES,PMULL} and {SHA1,SHA256} separately.\n\nAlso standardize on __ARM_NEON, which is the recommended symbol from\nACLE, and the only one defined on non-Apple aarch64 targets. Digging\nthrough GCC history, __ARM_NEON__ is a bit older.  __ARM_NEON was added\nin GCC\u0027s 9e94a7fc5ab770928b9e6a2b74e292d35b4c94da from 2012, part of GCC\n4.8.0.\n\nI suspect we can stop paying attention to __ARM_NEON__ at this point,\nbut I\u0027ve left both working for now. __ARM_FEATURE_{AES,SHA2} is definite\ntoo new to fully replace __ARM_FEATURE_CRYPTO.\n\nTested on Linux that -march\u003darmv8-a+aes now also drops the fallback AES\ncode. Previously, we would pick up -march\u003darmv8-a+crypto, but not\n-march\u003darmv8-a+aes. Also tested that, on an OPENSSL_STATIC_ARMCAP build,\n-march\u003darmv8-a+sha2 sets the SHA-1 and SHA-256 features.\n\nChange-Id: I749bdbc501ba2da23177ddb823547efcd77e5c98\nReviewed-on: https://boringssl-review.googlesource.com/c/boringssl/+/50847\nReviewed-by: Adam Langley \u003cagl@google.com\u003e\n",
