Dear testers, Release Candidate 3 has just been tagged [1]. Please build, test, and upload to the sftp. If there are no regressions from previous release candidates, this will be the last release candidate before the final release. Release notes can still go into the branch. Thanks again for all your work! Hans [1] http://lists.llvm.org/pipermail/llvm-branch-commits/2016-February/009866.html

Hi, I've tagged 3.8.1-rc1, testers can begin testing. -Tom

The CentOS Atomic SIG has released an updated version (https://wiki.centos.org/SpecialInterestGroup/Atomic/Download) of CentOS Atomic Host (7.1708), a lean operating system designed to run Docker containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux...

I've run into some issues with the current atom object model that I would like to fix. The current 4 atoms are not expressive enough. We need to be able to serialize a larger set of atoms, many of which are format specific. The set of common atoms (shared between all formats) should be the set that the resolver requires to work. SharedLibrary...

The documentation for is.atomic and is.recursive is inconsistent with their behavior in R 2.9.1 Windows. ? is.atomic ???? 'is.atomic' returns 'TRUE' if 'x' is an atomic vector (or 'NULL') ???? and 'FALSE' otherwise. ???? ... ???? 'is.atomic' is true for the atomic vector types (...

Right now, the atomics implementation in clang is a bit of a mess. It has three basically completely distinct code-paths: There's the legacy __sync_* builtins, which clang lowers directly to atomic IR instructions. Then, the llvm atomic IR instructions themselves can sometimes emit libcalls to __sync_* library fun...

I don't have much of substance to add, but I will say that I like the proposal (I too prefer Alternative A). When adding C11 atomic support for hexagon, I found it surprising that support for the __sync_* was implemented completely differently than the C11 atomics.

Any plans for using Atom with rails. I saw the "Typo" project is using MoveableType, Blogger, ... but not Atom. It seems Atom is not part of ActionWebService. Has anyone done any work with Atom and Rails ? Thanks for your answers, Gaspard

Hi llvm-dev, I read about volatile and atomic modifiers in the docs[1], and I feel they make sense to me individually. However, I noticed that store[2] and load[3] instructions can be marked as both volatile and atomic. What's the use case for using both volatile and atomic on an instruction? Isn't it the case that atomic implies vo...

I support Nick's option too. I think handling groups is another example of using follow on references. One question is how does an atom outside the group refer to the main atom here ? Will not garbage collection cleanup the main atom/signature atom because there are no references ?
