+ * x86-64 optimized assembler MD5 implementation

+ * Author: Marc Bevand, 2004
+ *
+ * This code was placed in the public domain by the author. The original
+ * publication can be found at:
+ *
+ * https://www.zorinaq.com/papers/md5-amd64.html
+ */
+/*
+ * No modifications were made aside from changing the function and file names.
+ * The MD5_CTX structure as expected here (from OpenSSL) is binary compatible
+ * with the md_context used by rsync, for the fields accessed.
+ *
+ * Benchmarks (in MB/s) C ASM
+ * - Intel Atom D2700 302 334
+ * - Intel i7-7700hq 351 376
+ * - AMD ThreadRipper 2950x 728 784
+ *
+ * The original code was also incorporated into OpenSSL. It has since been
+ * modified there. Those changes have not been made here due to licensing
+ * incompatibilities. Benchmarks of those changes on the above CPUs did not
+ * show any significant difference in performance, though.
