[llvm-dev] LLVM-4.0.1 build problem on Linux

[Mehdi AMINI via llvm-dev]

Hi,

It seems that your linker was killed during its process, likely because
out-of-memory. Here are a few tips:

- Are you building in parallel? One thing would be to reduce the
parallelism level.
- By default linux distribution are using the bfd linker, try to switch to
gold instead (cmake -DLLVM_USE_LINKER=gold) it is usually a lot more
performant.
- Build with optimization and without debug info: cmake
-DCMAKE_BUILD_TYPE=Release.

Hope this'll help!
