As announced here, the new LLVM release is now available. If you are interested after reading the release notes (or the clang ones), I just added the corresponding packages in Gentoo, although still masked for some additional testing. mesa-11.0 release candidates compile fine with it though.
2015/09/04 edit: llvm 3.7.0 is now unmasked!
On the Gentoo side, this version bump has some nice changes:
- We now use the cmake/ninja build system: huge thanks to fellow developer mgorny for his hard work on this rewrite. This is the recommended build system upstream now, and some features will only be available with it
- LLDB, the debugger is now available via USE=lldb. This is not a separate package as the build system for llvm and subprojects is quite monolithic. clang is in the same situation: sys-devel/clang package currently does almost nothing, the magic is done in llvm[clang])
- These new ebuilds include the usual series of fixes, including some recent ones by gienah
On the TODO list, some tests are still failing on 32bit multilib (bug #558604), ocaml doc compilation/installation has a strange bug (see the additional call on docs/ocaml_doc target in the ebuild). And let’s not forget adding other tools, like polly. Another recent suggestion: add llvm’s OpenMP library needed for OpenMP with clang.
Also, if people were still using the dragonegg GCC plugin, note that it is not released anymore upstream. As 3.6.x versions had compilation problems, this package received its last rites.
