You do understand that hardware development has been shaped by C being the defacto standard low-level language? That is, if new hardware isn't easy to code for with C it has little chance of it catching on, unless it's so incredibly low-level and minimal that ASM is the most complicated language you need. And while I'm no compiler writer, I suspect stack machines are a great choice for modelling an intermediate language because converting it to optimal register use is fairly simple, yet at the same time is completely agnostic about how many registers an underlying machine has. |

No, I don't understand that, and honestly have no clue what you're talking about. C is about as simple as things come, and it doesn't necessarily make strange demands on the hardware. It may seem that I'm contradicting my previous statement, but C working well with hardware doesn't necessarily mean it is a force for shaping modern hardware.
Three operand register-based load / store machines make too much sense from a variety of angles for many (any?) other configurations to touch them, that's why they're everywhere.
Stack machines are inherently less efficient, and you only see a bunch of designs (mostly as amateur soft cores) to this day because they are almost trivial to for enthusiasts to implement, not because they kick ass.
