H A D | sha512_generic.c | f2ea0f5f Sat Jan 14 12:44:49 CST 2012 Alexey Dobriyan <adobriyan@gmail.com> crypto: sha512 - use standard ror64()
Use standard ror64() instead of hand-written. There is no standard ror64, so create it.
The difference is shift value being "unsigned int" instead of uint64_t (for which there is no reason). gcc starts to emit native ROR instructions which it doesn't do for some reason currently. This should make the code faster.
Patch survives in-tree crypto test and ping flood with hmac(sha512) on.
