* Flatten ZSTD_row_getMatchMask * Remove the SIMD abstraction layer. * Add big endian support. * Align `hashTags` within `tagRow` to a 16-byte boundary. * Switch SSE2 to use aligned reads. * Optimize scalar path using SWAR. * Optimize neon path for `n == 32` * Work around minor clang issue for NEON (https://bugs.llvm.org/show_bug.cgi?id=49577) * replace memcpy with MEM_readST * silence alignment warnings * fix neon casts * Update zstd_lazy.c * unify simd preprocessor detection (#3) * remove duplicate asserts * tweak rotates * improve endian detection * add cast there is a fun little catch-22 with gcc: result from pmovmskb has to be cast to uint32_t to avoid a zero-extension but must be uint16_t to get gcc to generate a rotate instruction.. * more casts * fix casts better work-around for the (bogus) warning: unary minus on unsigned
