With the fixed version I do get a 2x speedup on Intel, and this despite it's only SSE2 (because Apple's silly OSX assembler can't handle AVX and stuff).
$ ../run/john -t -fo:raw-sha512*
Benchmarking: Raw SHA-512 [128/128 SSE2 intrinsics 2x]... DONE
Raw: 2890K c/s real, 2890K c/s virtual
Benchmarking: Raw SHA-512 [64/64 CommonCrypto]... DONE
Raw: 1449K c/s real, 1449K c/s virtual
...and just over 2x on Bull:
$ ../run/john -t -fo:raw-sha512*
Benchmarking: Raw SHA-512 [128/128 XOP intrinsics 2x]... DONE
Raw: 3813K c/s real, 3778K c/s virtual
Benchmarking: Raw SHA-512 [64/64 OpenSSL]... DONE
Raw: 1889K c/s real, 1889K c/s virtual
