MCJit Runtine Performance
Hi All,
We recently upgraded a number of applications from LLVM 3.5.2 (old JIT)
to LLVM 3.7.1 (MCJit).
We made the minimum changes needed for the switch (no changes to the IR
generated or the IR optimizations applied).
The resulting code pass all tests (8000+).
However the runtime performance dropped significantly: 30% to 40% for
all applications.
The applications I am talking about

Hi Morten,
Something else just occurred to me: can you share your EngineBuilder configuration lines? (http://llvm.org/docs/doxygen/html/classllvm_1_1EngineBuilder.html)
In particular - are you explicitly setting the optimization level? The old JIT may have had a different default.
- Lang.
