! 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.
