* Revert AltiVec and Power8 commitsJeffrey Walton2017-09-051-11/+11
| | | | | The strategy of "cleanup under-aligned buffers" is not scaling well. Corner cases are still turing up. The library has some corner-case breaks, like old 32-bit Intels. And it still has not solved the AltiVec and Power8 alignment problems. For now we are backing out the changes and investigating other strategies
* Fixup under-aligned buffers for DefaultEncryptors and DefaultDecryptors on ↵Jeffrey Walton2017-09-041-11/+11
| | | | | | | | | | AltiVec and Power8 This commit supports the upcoming AltiVec and Power8 processor support for DefaultEncryptors and DefaultDecryptors. The commit favors AlignedSecByteBlock over SecByteBlock in places where messages are handled on the AltiVec and Power8 processor data paths. The data paths include all block cipher modes of operation, and some filters like FilterWithBufferedInput. Intel and ARM processors are tolerant of under-aligned buffers when using crypto intstructions. AltiVec and Power8 are less tolerant, and they simply ignore the three low-order bits to ensure an address is aligned. The AltiVec and Power8 have caused a fair number of wild writes on the stack and in the heap. Testing on a 64-bit Intel Skylake show a marked improvement in performance. We suspect GCC is generating better code since it knows the alignment of the pointers, and does not have to emit fixup code for under-aligned and mis-aligned data. Testing on an mid-2000's 32-bit VIA C7-D with SSE2+SSSE3 showed no improvement, and no performance was lost.
