The generated machine code I've seen does not make use of this. All the load/store instructions in vectorized or unrolled loops assume unaligned pointers. (Plus, with AVX one should align to 32 bytes instead.) -erik -- Erik Schnetter <schnet...@cct.lsu.edu> http://www.perimeterinstitute.ca/personal/eschnetter/
