LLVM includes n^2 copies of the clang version in .comment sections.

Applications running the compiled runtime on Linux can experience high memory usage and long compilation times. When using a compilation cache, then they can also experience very large cache directories. This happens with complex EPL applications with very deep dependency graphs between EPL types. Redundant object file information has been removed, improving the size of cache directories, injection times and memory usage for the compiled runtime.
