--- Comment #15 from vries at gcc dot gnu.org --- (In reply to vries from comment #3) > [ There's a problem with the matching. The rs in "..rrr" were supposed to > match the PTR_PTR_PTR arguments. But that's not the case, since we need to > add a dot even for a void result. So the intended spec string was "...rrr". > AFAIU, this problem does not affect this PR. But I will review > omp-builtins.def for similar problems. ] Fixed in https://gcc.gnu.org/ml/gcc-patches/2015-06/msg00089.html
