From the top of my head: LLVM: - lack of udis86 support (optional dep), - bundled libgtest installed (for now, i'm just removing it in src_install), - circa 3 test failures (none with autoconf), - no support for building ocaml bindings [thought i'll probably split them into separate package and find a way to build somehow then, just haven't got time to look into it yet], - installed cmake modules refer to the build-dir (/var/tmp/portage/.../llvm...). compiler-rt: - needs to be built from llvm sources (needs to be fixed upstream), - enabling tests and compiler-rt on llvm at the same time requires clang, and symlinking clang into the build tree causes -Werror-like build failures). clang: - [old issue] looks for some of its files during runtime (gold? libs? i don't remember) in 'lib' rather than $(get_libdir), - builds clang-tblgen in LLVM temporary build-dir stored in the cmake modules -> wreaks havoc if you build llvm & clang at the same time, - i haven't checked the test suite yet. That's what I can recall right now :P.
New issues: llvm: - FileCheck is installed with insecure RUNPATH (it's installed by hand so probably necessary to make cmake install them). clang: - a lot of test failures after enabling tests.
FileCheck is used in tests for dragonegg (bug #445680)
(In reply to comment #2) > FileCheck is used in tests for dragonegg (bug #445680) clang uses it too. That's why I added it to the ebuild. The issue is that it probably needs to be installed using cmake rather than by hand.
