There is a nice description of pure in byte-opt.el

    ;; pure functions are side-effect free functions whose values depend
    ;; only on their arguments. For these functions, calls with constant
    ;; arguments can be evaluated at compile time. This may shift run
    ;; time errors to compile time.
