Either way, I don't see any justification to reject the idea of having 2-arg opcodes because of speed, which is what the original post seemed to be saying. Or maybe I misunderstood.
The latter. I was objecting to Guido's suggestion to time it and see... I'm not opposed to the idea, although it is likely to slow things down. But assuming we don't talk about performance, I don't see a reason for not thinking about a generalized scheme with variable-size arguments, (cf. classical CPU instruction sets) that is, instructions which operate on 1-, 2- or 4-byte arguments. if-you-wanna-fix-it-do-it-like-a-man-<wink>'ly y'rs -- Vladimir MARANGOZOV | Vladimir.Marangozov@inrialpes.fr http://sirac.inrialpes.fr/~marangoz | tel:(+33-4)76615277 fax:76615252
