  SIMD in zlib-rs (part 2): compare256

  In part 1 of the "SIMD in zlib-rs" series, we've seen that, with a bit of nudging, autovectorization can produce optimal code for some problems. But that does not always work: with SIMD clever programmers can still beat the compiler.

  SIMD in zlib-rs (part 1): Autovectorization and target features

  I'm fascinated by the creative use of SIMD instructions. When you first learn about SIMD, it is clear that doing more multiplications in a single instruction is useful for speeding up matrix multiplication. But how can all of these weird instructions be used to solve problems that aren't just arithmetic?
