- * Best performance comes from most recent compilers, with intrinsics and -O3.
- * Must compile with -march=armv8.2-a+sha3, but we can't detect armv8.2-a, and
- * can't always detect __ARM_FEATURE_SHA512 (notably clang 7-12).
- *
- * GCC < 8 won't work at all (lacks the sha512 instructions)
- * GCC >= 8 uses intrinsics, sets __ARM_FEATURE_SHA512
- *
- * Clang < 7 won't work at all (lacks the sha512 instructions)
- * Clang 7-12 don't have intrinsics (but we work around that with inline
- *            assembler) or __ARM_FEATURE_SHA512
- * Clang == 13.0.0 same as clang 12 (only seen on macOS)
- * Clang >= 13.0.1 has __ARM_FEATURE_SHA512 and intrinsics
