12: * No modifications were made aside from changing the function and file names.
13: * The MD5_CTX structure as expected here (from OpenSSL) is binary compatible
14: * with the md_context used by rsync, for the fields accessed.
15: *
16: * Benchmarks (in MB/s) C ASM
17: * - Intel Atom D2700 302 334
18: * - Intel i7-7700hq 351 376
19: * - AMD ThreadRipper 2950x 728 784
20: *
21: * The original code was also incorporated into OpenSSL. It has since been
22: * modified there. Those changes have not been made here due to licensing
23: * incompatibilities. Benchmarks of those changes on the above CPUs did not
24: * show any significant difference in performance, though.
