Aah. I didn't realize Dalvik's VM was that different. I thought that, like the libraries, it was also a subset. (and, yes, I understand register based vs stack based ... I cut my assembly teeth on VAX-11 assembler ... and, RISC vs CISC isn't exactly register vs stack ... there were pre-RISC stack based architectures, and I think (but am not sure) that there are register based RISC architectures, as well)
