IBM's investment in LLVM and Clang open source technology is not a cost cutting measure, it is the opposite; IBM is increasing overall investment in compiler technology and improving LLVM in general, as evidenced by recent contributions to AIX enablement and loop optimizations. By leveraging this very robust and successful open source compiler infrastructure, IBM can prevent duplication of effort as much as possible.
