Faust compiling for MIR about mir HOT 3 OPEN

Stephane, thank you very much for trying MIR and provided performance data!

I do have plans to port MIR to more targets. I am planning to port MIR ppc64 and z-series before the summer. I am thinking about making the first MIR release this summer too.

As for the performance, loop invariant code motion and register renaming (for better register allocation and better invariant code motion) will be added and ready in about 1-2 months. I hope this will improve the performance a bit.

Can you explain what the figures mean? Is higher bar better or worse?

C++ is the reference (= 1), higher is better. So basically on the tests MIR run between 31% (violonMIDI.dsp) up to 83% (mixer.dsp) of the C++ version.
C++ and LLVM IR code is emitted on native mode (equivalent to -march=native) and -Ofast. C++ and LLVM may also auto-vectorize.
