...n will be applied to all examples should also work for the IR pass examples. I think he would like to remove LLVM_BUILD_EXAMPLES altogether. That is, any "cmake" will execute any CMakeLists.txt, "make all" will always build TutorialSimplyCFG and any execution of `opt` will call initializeExampleIRTransforms. I am in favor of adding (more) tutorials to the repository, joint trying to point out items to consider. Michael

...be valuable to have the code examples for various tutorials in-tree to keep them from bit-rotting and make it very easy to build them. I’d suggest adding new IR pass examples to llvm/examples/IRTransforms. The passes in that directory will be built as an ExamplesIRTransforms library, which exposes initializeExampleIRTransforms to initialise the passes. Additionally, if LLVM_BUILD_EXAMPLES=On, we add a -DBUILD_EXAMPLES define, which is then used in opt to make the example passes available if LLVM_BUILD_EXAMPLES=On. I think that allows for relatively friction-less integration of the example passes into `opt`. I’ve put up...
