- * are in this case of the same "endianness" these two are
- * otherwise indistinguishable. But normally you don't want to
- * call the same function because unaligned access in places
- * where alignment is expected is usually a "Bad Thing". Indeed,
- * on RISCs you get punished with BUS ERROR signal or *severe*
- * performance degradation. Intel CPUs are in turn perfectly
- * capable of loading unaligned data without such drastic side
- * effect. Yes, they say it's slower than aligned load, but no
- * exception is generated and therefore performance degradation
- * is *incomparable* with RISCs. What we should weight here is
- * costs of unaligned access against costs of aligning data.
- * According to my measurements allowing unaligned access results
- * in ~9% performance improvement on Pentium II operating at
- * 266MHz. I won't be surprised if the difference will be higher
- * on faster systems:-)
