Re: [Fink-devel] llvm/llvm-gcc42-2.5-1 on fink tracking
Peter, You totally misunderstand the purpose of bundling the libLTO.dylib with the llvm-shlibs package. It is only there to give the user the option to manually replace Apple's libLTO.dylib with that from the llvm-2.5 sources if they want to explore the complete functionality of LTO. I never said that these packages would automatically replace the system libLTO.dylib, only that they would provide a copy for the use to try if they were so inclined.

[Fink-devel] llvm/llvm-gcc42-2.5-1 on fink tracking
FYI, I have uploaded packaging for llvm/llvm-gcc42-2.5-1 packaging onto fink tracking. I have created a llvm package so that we can have access to the llvm tool chain including bugpoint (for reporting bugs back to the llvm developers). The gfortran 4.2.1 compilers in the llvm-gcc42 package now pass all of the Polyhedron 2005 benchmarks so they are usable now. The llvm-shlibs package provides a copy of the libLTO.dylib file built by llvm 2.5. This can be used to replace that from Xcode 3.2.1 in /Developer/usr/lib to provide fuller LTO options. The libLTO.dylib in Xcode 3.2.1 only supports dead code elimination at -O4 whereas the libLTO.dylib in llvm 2.5 provides additional optiminizations like inlining across code files. The packaging currently on fink tracking use the llvm/llvm-gcc-4.2 2.5 prerelease source code but when 2.5 is finally released, I will push these packages into fink 10.4 unstable.
