* OCB optimizationsJack Lloyd2017-10-132-58/+90
| | | | | | With fast AES-NI, gets down to about 2 cycles per byte which is pretty good compared to the ~5.5 cpb of 2.3, still a long way off the best stiched impls which run at ~0.6 cpb.
* Somewhat faster xor_bufJack Lloyd2017-10-121-18/+15

* Swapped encrypt and decrypt in BlockCipher _xex functionsJack Lloyd2017-10-121-2/+2
| | | | | Missed by everything but the OCB wide tests because most ciphers have fixed width and get the override.

| * Ugh, the GCC/Clang trick triggers C4146 under MSVCJack Lloyd2017-10-121-8/+25
| | | | | | | | | | | | And rotate.h is a visible header. Blerg. Inline asm it is.
| * Add compile-time rotation functionsJack Lloyd2017-10-1236-677/+716
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem with asm rol/ror is the compiler can't schedule effectively. But we only need asm in the case when the rotation is variable, so distinguish the two cases. If a compile time constant, then static_assert that the rotation is in the correct range and do the straightforward expression knowing the compiler will probably do the right thing. Otherwise do a tricky expression that both GCC and Clang happen to have recognize. Avoid the reduction case; instead require that the rotation be in range (this reverts 2b37c13dcf). Remove the asm rotations (making this branch illnamed), because now both Clang and GCC will create a roll without any extra help. Remove the reduction/mask by the word size for the variable case. The compiler can't optimize that it out well, but it's easy to ensure it is valid in the callers, especially now that the variable input cases are easy to grep for.
| * Use rol/ror x86 instructions on GCC/ClangJack Lloyd2017-10-111-2/+24
| | | | | | | | | | | | | | Neither is very good at recognizing rotate sequences. For cases where the rotation value is a constant they do fine, but for variable rotations they do horribly. Using inline asm here improved performance of both CAST-128 and CAST-256 by ~20% on my system with both GCC and Clang.
