#23580: odcctools: update to support LTO -------------------------------+-------------------------------------------- Reporter: macports@… | Owner: macports-tickets@… Type: update | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.2 Keywords: llvm lto | Port: odcctools -------------------------------+-------------------------------------------- To enable -O4 and -flto [http://llvm.org/docs/LinkTimeOptimization.html link time optimization] in clang and llvm-gcc we need a linker with support for llvm bitcode. Newer versions of the [http://opensource.apple.com/source/ld64/ ld64 linker] (>=v77) can be configured to include such support through libLTO.dylib. The recent release of [http://svn.macosforge.org/repository/odcctools/release/ odcctools-20090808] comes bundled with ld64 v85. Updating the odcctools port would be very helpful, see #19679. [http://lists.apple.com/archives/Darwin-dev/2009/Sep/msg00025.html Note that the latest source releases v95 through v96.5 of ld64 are known to be incomplete and wont work]. -- Ticket URL: <http://trac.macports.org/ticket/23580> MacPorts <http://www.macports.org/> Ports system for Mac OS
