--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Also note that even at -O0, at no point during compilation with GCC/G++ if the
value of ++a or a++ isn't used and a has integral/pointer type one form is more
efficient than the other. It is just a different tree code
({PRE,POST}{IN,DE}CREMENT_EXPR), but with the same operand, type etc.
So, there is no waste of any resources, it is not a defect to use either style,
it is purely coding convention matter.
