--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Nobody is blocking proper double double evaluation support. But somebody needs to do the work, spend a few weeks on it and submit that. I'm just saying that is highly unlikely. If somebody was really bothered about that there wouldn't be 19 years of it being unfixed. More so in the years when it was the typical long double on Linux powerpc64le as well. It is still the usually supported long double on Linux powerpc64 and powerpc, but those are rarely used these days.
