ΒΆvoid FindFunctionBackedges(
    const llvm::Function& F,
    SmallVectorImpl<std::pair<const BasicBlock*,
                              const BasicBlock*>>&
        Result)

Description

Analyze the specified function to find all of the loop backedges in the function and return them. This is a relatively cheap (compared to computing dominators and loop info) analysis. The output is added to Result, as pairs of <from ,to> edge info.

Declared at: llvm/include/llvm/Analysis/CFG.h:33

Parameters

const llvm::Function& F
SmallVectorImpl<std::pair<const BasicBlock*, const BasicBlock*>>& Result
