It would be nice to have clang/llvm in Gentoo Prefix. I have tested the following ebuilds from the main repository with the help of the eapify-script on an ~amd64-linux - target: sys-devel/llvm-2.7 and sys-devel/llvm-9999 with the use-flags +libffi +alltargets +debug +ocaml. I'm not interested in llvm-gcc, so i have not tested +llvm-gcc. +udis86 is not possible because dev-libs/udis86 is missing in the prefix. (I have not tried to add udis86 to the prefix.) sys-devel/clang-2.7 (+-system-cxx-headers) and sys-devel/clang-9999 with +debug +static-analyzer. Everything compiles just fine. I only tested some minor parts for functionality: clang and clang++ is able to produce executable (and functional) code for some simple and two bigger projects I tried to compile. I only stumbled over non prefix - specific issues, e.g. the need to compile clang-2.7 with +system-cxx-headers so that clang++ finds the STL-Headers. (This issue should be addressed in the latest svn-version, so -9999 is just fine.) Reproducible: Always
Please review and comment on the changes to clang-2.7-r2, necessary for Prefix support. The install_name_tool bit is to accomodate Darwin installs only.

Please upload the patch as an attachment, due to the line-wrapping in Bugzilla this patch is malformed.
Created attachment 244047 [details, diff] clang-2.7-r2-prefix.patch it was meant for review only, I can just commit it when ok, but here you go
Created attachment 244167 [details, diff] Proposed clang-9999.ebuild for prefix This is Fabian's patch applied to the 9999-ebuild. (It would be very nice to have the svn-version in the prefix too :) ) Compiles and runs fine on a ~amd64-linux - host. Can someone with a Darwin - target please review whether the changes work as intended?
Close to llvm changes, these are also good for me!
committed, thanks!
