◆ run()

PreservedAnalyses LowerExpectIntrinsicPass::run ( Function F,

Run the pass over the function.

This will lower all of the expect intrinsic calls in this function into branch weight metadata. That metadata will subsequently feed the analysis of the probabilities and frequencies of the CFG. After running this pass, no more expect intrinsics remain, allowing the rest of the optimizer to ignore them.
