I'm looking at parameterizing the g++ ABI, and am strongly considering that as an implementation strategy. I started to reply, but then I realized that it depends upon what you mean by the g++ ABI. Do you mean the code that g++ generates, or do you mean the files in gcc/cp? The former already uses jumptables, of course, since that's what virtual functions are, and I'm not sure in what sense the latter has an ABI. Ian
