Jeffrey Walton	19deccf3ba	Fix Clang 5.0 "runtime error: addition of unsigned offset to 0xXXXX overflowed to 0xYYYY" (GH #549 )	2017-12-16 18:18:53 -05:00
Jeffrey Walton	dc21de2483	Fix UBsan overflow finding We were cating UBsan findings under Clang similar to "adv-simd.h:1138:26: runtime error: addition of unsigned offset to 0x000002d41410 overflowed to 0x000002d41400". The problem was CRYPTOPP_CONSTANT, which used an enum. The compiler is allowed to pick the underlying data type, and Clang was picking a signed type	2017-12-16 14:21:08 -05:00

Jeffrey Walton	8a5911e6eb	Refactor <cipher>_AdvancedProcessBlocks_<arch> into adv-simd.h This also fixes the SPECK64 bug where CTR mode self tests fail. It was an odd failure because it only affected 64-bit SPECK. SIMON was fine and it used nearly the same code. We tracked it down through trial and error to the table based rotates.	2017-12-09 21:04:25 -05:00
