ok. I guess you mean __m128i, for that particular case.

It very much seems that the texinfo documentation for this part of gcc is to be
forgotten for good, then.

Sure -- this I gathered from previous PR in the same area. Which leaves pending
the question of documenting ``right'' vs ``wrong'' ;-).


I've ranted some rubbish above -- the psrlq builtins and friends are still
completely there indeed, I just missed the fact that commit 123250 reverted
commit 123215, which I expected at first to have broken things.
