So, LLVM_ENABLE_LTO is not available for LLVM/Clang v3.8.0?! Hmm, maybe I can backport (or git cherry-pick) SVN r259766. - Sedat - [1] http://llvmweekly.org/issue/110 [2]...

I don’t think cmake accept “LDFLAGS” directly, instead it is using “CMAKE_MODULE_LINKER_FLAGS”, “CMAKE_SHARED_LINKER_FLAGS”, and “CMAKE_EXE_LINKER_FLAGS”. Ideally these would be set automatically when building LLVM with -DLLVM_ENABLE_LTO=THIN. Teresa, I think it would be valuable to update llvm/cmake/modules/HandleLLVMOptions.cmake and make sure 1) either LLD or GOLD is used, 2) add the relevant plugin flags if nee...

Hi all. I want to use llvm in my project and I want to make llvm a git submodule in my project. http://llvm.org/docs/CMake.html#embedding-llvm-in-your-project At this in the documentation it claims to describe how to embed llvm into a project. I tried it that way but it doesn't work, because there isn't any findLLVM.cmake in the llvm/cmake/modules directory anymore (i don't

​Hi again, Teresa. Looks like I had forgotten to report back with success when finally building 3.9.0 in ThinLTO linker mode back in October. Sorry about that and thanks for helping me out. I know how important it is to get success reports as well, as a developer myself, so sorry again :(. While that worked back then, last weekend I tried to build 3.9.1 using 3.9.0 as installed from Arch Linux

That seems to work (see below). $ cd

I had only a quick view on the blog-texts. It might be that a CLANG generated with LTO/PGO speeds up the build. Can you confirm this? Can you confirm binutils-gold speed up the build? Has LLVM an own linker? Can be used? Speedup the build? Yesterday night I loooked through available CMAKE/LLVM variables... ### GOLD # CMAKE_LINKER:FILEPATH=/usr/bin/ld #
