In tests so far, this is much, much slower than either the standard scalar code, or using the SIMD-in-scalar-registers code. It looks like for whatever reason GCC is refusing to inline the function: SIMD_Altivec(__vector unsigned int input) { reg = input; } and calls it with a branch hundreds of times in each function. I don't know if this is the entire reason it's slower, but it definitely can't be helping. The code handles unaligned loads OK but assumes stores are to an aligned address. This will fail drastically some day, and needs to be fixed to either use scalar stores, which (most?) PPCs will handle (if slowly), or batch the loads and stores so we can work across the loads. Considering the code so far loads 4 vectors of data in one go this would probably be a big win (and also for loads, since instead of doing 8 loads for 4 registers only 5 are needed).

Also add a pure scalar code version. Convert Serpent to use this new interface, and add an implementation of XTEA in SIMD. The wrappers plus the scalar version allow SIMD-ish code to work on all platforms. This is often a win due to better ILP being visible to the processor (as with the recent XTEA optimizations). Only real danger is register starvation, mostly an issue on x86 these days. So it may (or may not) be a win to consolidate the standard C++ versions and the SIMD versions together. Future work: - Add AltiVec/VMX version - Maybe also for ARM's NEON extension? Less pressing, I would think. - Convert SHA-1 code to use SIMD_32 - Add XTEA SIMD decryption (currently only encrypt) - Change SSE2 engine to SIMD_engine - Modify configure.py to set BOTAN_TARGET_CPU_HAS_[SSE2|ALTIVEC|NEON|XXX] macros
