[llvm-dev] Manually Constructing LoopInfo via Dominator Tree
Hi, I noticed one of the earlier posts (https://groups.google.com/g/llvm-dev/c/lVc2-0d2cRs/m/uwuOA_pXAgAJ) from llvm-dev that talked about "constructing loop info manually without any pass" by doing this: llvm::DominatorTree domTree{&func, func}; llvm::LoopInfo loopInfo{&func, domTree}; However, when I try this in llvm 10.0, I get the following error: error: no matching function for call to ‘llvm::DominatorTree::DominatorTree(<brace-enclosed initializer list>)’ DominatorTree domTree{&F, F}; Am I doing something really silly here? or this manual hack no longer works? Thanks, Bodhi

[llvm-dev] Manually Constructing LoopInfo via Dominator Tree
DominatorTree has the following constructor: explicit DominatorTree(Function &F); That is, use llvm::DominatorTree DT(func); to instantiate it. Michael Am Mi., 15.
