The first complete Pascal compiler I wrote was targeted for a stack
machine, and it was a real pain after having written phases of other
compilers for non-stack targets.
The biggest drawback is the 0-operand mode of the stack architecture
vs. 2- or 3-operand mode with register operands. The LIFO nature of
the stack leads to much larger code generated, even after optimiza-
tion, than with registers.
Yes, it is true that being stack-based frees you from the pitfalls
of register-based code, but you also lose the advantages.
