...gives no output.
So, LLVM_ENABLE_LTO is not available for LLVM/Clang v3.8.0?!
Hmm, maybe I can backport (or git cherry-pick) SVN r259766.

What is your exact cmake invocation?
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 need...

Embedding llvm as a git submodule in Project
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

(Thin)LTO llvm build
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

Hi Chris,
thanks for the response!
That seems to work (see below).

Building with LLVM_PARALLEL_XXX_JOBS
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...

Asan self host problems: Failed to deallocate
Trying to run a self host "ninja check-clang" with ASan enabled I hit a
/lot/ of errors like this (strangely I hit none of these in check-llvm,
only in check-clang):
Any ideas?
