The RISC core of every x86 since PPro is a load/store machine.

Those instructions still aren't exposed to the user, are they?

[kevin_thibedeau]

Doesn't matter. The core doesn't see the x86 instructions either. MOVs are decoded into simpler operations to facilitate reordering.

Good luck decoding LOCK CMPXCHG to loads and stores.

In any case, my actual objection was to “LOAD instruction in x86”. It makes no sense.
