It turns out ck already has equivalent primitives. Pardon the noise. -M On Sat, Jun 23, 2018 at 12:18 Matthew Macy wrote: > The functions in the subject are both documented in atomic(9) and are > implemented by every arch except sparc64 and MIPS.

atomic_testandclear_, atomic_testandset_
The functions in the subject are both documented in atomic(9) and are implemented by every arch except sparc64 and MIPS. I have some code in review that uses them that I intend to commit once the various design issues are addressed. Please implement them so that those targets can remain part of universe. Thanks in advance. -M ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
