[LLVMdev] Some MCJIT benchmark numbers
...at the profiling results, it looks like about
47% of the time is spent in PassManagerImpl::run, and another 47% is spent
in addPassesToEmitMC, which feels like it could be avoided by doing that
just once. Of the time spent in PassManagerImpl::run, about 35% is spent
in PassManager overhead such as initializeAnalysisImpl() /
removeNotPreservedAnalysis() / removeDeadPasses().
For 10k iterations, the test took about 12.6s, or 1.26ms per module, so
there's definitely some slowdown happening. Looking at the profiling
output, it looks like the main difference is the appearance of
MCJIT::finalizeLoadedModules(), wh...
