...rt to warn about atomics being unavailable and thus building thread-unsafe. I just looked into it and found an easy solution, using the atomic functions in <libkern/OSAtomic.h> in /usr/include. The attached patch does this and also modifies the cmake and autoconf tests to 'pass' LLVM_HAS_ATOMICS. I'm able to build LLVMSupport.dylib with this patch. Please review, revise, criticize?

This file is for configure+make build, not CMake, so I'm not sure why it's being included into your build (these failures aren't reproducible for me). Can you please list the exact steps you're doing to build LLVM with CMake and make sure you don't have additional CFLAGS (LDFLAGS etc) defined?

Hallo all, I was trying to Build LLVM with the cmake option LLVM_ENABLE_MODULES just out of curiosity. I used the RELEASE_400/final tag. It didn't work as I almost expected. So I'm wondering if the modulemaps aren't maintained anymore? If they aren't maintained anymore, why aren't they removed and that cmake option also removed?

Hi, I'm trying to do a build and install on Windows 10 with Visual Studio 2015 Community Edition for the X86 and ARM targets, from the current release_40 branch. While compilation completes without error, the INSTALL target fails with the following error: 54> CMake Error at projects/compiler-rt/lib/builtins/cmake_install.cmake:34 (file): 54> file INSTALL cannot find 54>

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 #
