--- Comment #5 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to vries from comment #4) > I've tried to do something similar in cp_build_unary_op. Tentative patch: That seems very complicated. We know the arguments, so we know which has to be converted to what. You could probably make cp_build_unary_op call cp_build_binary_op and cp_build_modify_expr (expand ++v as v=v+1), but I expect something like the 1-liner in comment #3 should be enough, no?
