tracking clang updates

[Preston_B_]

I recently downloaded, from the git repo, and built the Cilk Plus/LLVM stuff.

Playing with the generated Clang using -v, it claims to be 3.9. Surprising since 3.9 isn't really available yet, and notes about Cilk Plus/LLVM suggest it's made from a branch in February 2016. The git repo doesn't show any updates since February either.

What's going on?

Thanks

I don't see any problems in the description at https://cilkplus.github.io.

There were some updates that merge clang/llvm "trunk" (or master) in February, and llvm log tells that "release_38" branch was created in January, meaning that "trunk" in February must be something newer than "release_38".

Back in February, the most recent version of LLVM was 3.7.1 Today, the most recent version is 3.8.1 But when I download and build the version hosted at cilkplus.github.io, it claims to be version 3.9 I guess it's not a problem per se, but it does make it hard to know what I've got and hard to plan.

Yes, it claims to be 3.9 which was not released at that time, but the version number for the trunk was actually 3.9. The log of cilkplus/llvm describes exactly that it merged trunk not any released version (e.g., release_38).

I just checked out the same llvm version (trunk) that was merged into cilkplus/llvm on 02/03/2016 (as described in the log), and CMakeLists.txt tells that it was 3.9:

if(NOT DEFINED LLVM_VERSION_MAJOR)
  set(LLVM_VERSION_MAJOR 3)
endif()
if(NOT DEFINED LLVM_VERSION_MINOR)
  set(LLVM_VERSION_MINOR 9)
endif()
