For an integer, if the pre-increment value isn't used, GCC at least will generate the same code, even with optimization turned off:

    int pre(int a) {                    int post(int a) {
      ++a;                                  a++;
      return a;                             return a;
    }                                   }

    pre:                                post:
    .LFB0:                              .LFB1:
