    Phoronix: Release Planning Is Underway For LLVM 7.0, Shipping In September

    Continuing LLVM release manager Hans Wennborg has begun discussing plans for the upcoming LLVM 7.0 release...

    Is there any guide on building llvm and then building Mesa using that llvm? Half a year period is quite huge, so having latest llvm for testing can be useful.

      I think it would be nice if LLVM were to be released every ~4 months instead of the current 6. There's always so much new stuff in every release, people would probably appreciate getting access to it earlier.

        That would only work if it didn't take them 4 months to accept a patch.

        I'd agree that a shorter release cycle would be great to at least get critical bugs fixed, building LLVM-svn isn't exactly a fun experience. I like the way Mesa handles these things with a bug fix release every couple of weeks if necessary. But then again, with a project as massive and widely used as LLVM that's probably impossible to maintain.

          Mesa can possibly ship forked llvm with fixes, and in the interim try to push them upstream. That's what Rust (rustc) compiler is doing. They rely a lot on cutting edge llvm features that aren't upstreamed yet and it can take a while to get them in the main codebase. So they simply use their llvm branch, but they push their changes upstream as soon as it's feasible.

          It's not ideal (what if something won't be accepted), but this way Mesa release cycle can be more flexible.

            And LLVM/Clang still behind GCC in implementing some important features such "scalar_storage_order" attribute.

            I guess our company will skip LLVM 7 release as well.

              You could look at the PKGBUILD on aur, they're quite clear, even if not for your distribution.

                That's one of my favourite things about arch... the build process for all the packages isn't hidden behind 9000 layers of deb helpers, everything is clear and simple.

                  I'll take a look, thanks.
