/*
* 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.
