Conversely, if you look at a language you can sometimes see for which processor it was designed. As noted by others, c was originally designed for the PDP-11. Because the PDP-11 has pre-decrement indirect, and post-increment indirect addressing modes, c has ++ and -- constructs to take advantage of the PDP-11 architecture. Likewise, the car and cdr of LISP have their analogues in the architecture of the machine on which LISP was first implemented. There are likely other examples, but I'll leave that to the language specialists.
