[Arnold Zwicky](//en.wikipedia.org/wiki/Arnold_Zwicky) and [Geoff Pullum](//en.wikipedia.org/wiki/Geoff_Pullum)'s paper ["Cliticization vs. inflection: English n't"](http://doi.org/10.2307/413900), published in the September 1983 issue of [_Language_](//en.wikipedia.org/wiki/Language_(journal)) (volume 59, number 3), indicates that _I'd've_ is possible (but _I'dn't_ is not).
