At least one arch I know of (FRV) had instructions that could atomically load/store register pairs or register quads, but they had to be pair- or quad-aligned (ie. 8- or 16-byte), which made for more efficient code if you could use them. I don't know whether any arch we currently support has features like this (I know some have multi-reg load/stores, but they seem to require only word-alignment). David
