Built on bull, and things look a little better.
oSSL speed 350
SSE2 speed 1080
SSE4 fails, but I will likely be switching from flat mode, to mixed mode.
Just fixed GATHER, and I get 1580/s on SSE4 build on bull, with the existing 'flat' input buffers. Not too bad. The old GATHER was not working (only used right now in raw-sha256-ng-i if MMX_LOAD is not defined). I fixed GATHER, and created GATHER_x2 for the double width buffers I am using in sha256crypt.
Jim.
