...nvoke the option from front end level, we need to merge it into the IR library. >Stepping back a bit, I’m also surprised by the decision to move away from synthetic testing when there’s still so much low-hanging fruit to pick using that technique. The example from https://reviews.llvm.org/D81939 illustrates this perfectly: in this case it’s not necessary to invent a new testing technique to uncover the bug, because simply running `./bin/llvm-lit -Dopt="opt -debugify-each" test/Transforms/DeadArgElim` finds the same issue. As I mentioned in the previous mail, I do really think...

Hi, I am sharing the proposal [0] which gives a brief introduction for the implementation of the LLVM DI Checker utility. On a very high level, it is a pair of LLVM (IR) Passes that check the preservation of the original debug info in the optimizations. There are options controlling the passes, that could be invoked from ``clang`` as well as from ``opt`` level. By testing the utility on the
