http://bugzilla.opensuse.org/show_bug.cgi?id=1073210 Bug ID: 1073210 Summary: Link Time Optimization doesn't work out of the box on 64 bit systems because of bfd-plugins path mixup Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.3 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Development Assignee: bnc-team-screening@forge.provo.novell.com Reporter: l.lunak@centrum.cz QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- When using LTO, linker is supposed to find a plugin for handling LTO in /usr/lib/bfd-plugins . And this path is hardcoded in sources, and it's "lib" even for 64 bit systems. However, neither GCC nor Clang/LLVM install their plugin there. GCC doesn't do anything with its plugin except for shipping it in its own directory, and LLVMGold is installed to /usr/lib64/bfd-plugins. So instead of LTO simply working when using -flto, one has to use gcc-ar/llvm-ar etc. to override the ar etc. which should work but don't because of this. I can easily submit fixed binutils and gcc packages to make them use /usr/lib64/bfd-plugins too, but I've first created this bugreport so that there's just one place for referring to this issue. Also I would first like to verify that this would indeed be the proper fix - is there any special reason why binutils hardcodes the "lib" there? -- You are receiving this mail because: You are on the CC list for the bug.
