On rakudo.org ([1]) pages, I have noticed that the pthread_barrier_*
POSIX API is missing from Cygwin. I took a look at NetBSD and FreeBSD
implementations of it. It seemed to me that creating POSIX barrier on
top of POSIX mutex and POSIX conditional variable is not that hard ([2]).
Now, the question is whether this is acceptable and whether it should be
part of Newlib or directly part of Cygwin?
IMO a barriers implementation would be welcome. winsup/cygwin/thread.cc
would be the place for it.
Second, if I should pursue that, or if anyone who knows either Newlib or
Cygwin better than I wants to mould the source into an acceptable form.
I would not mind somebody else doing it. :D
PTC. :-)
I have, in the past, contributed small patches to Cygwin and I had done
the necessary copyright assignment paper work, so copyright should not
be a problem.
That would certainly be a prerequisite.
