As discussed on the RFC [0], I am sharing the set of patches that enables checking of original Debug Info metadata preservation in optimizations. The proof-of-concept/proposal can be found at [1]. The implementation from the [1] was full of duplicated code, so this set of patches tries to merge this approach into the existing debugify utility. For example, the utility pass in the original-debuginfo-check mode could be invoked as follows: $ opt -verify-debuginfo-preserve -pass-to-test sample.ll Since this is very initial stage of the implementation, there is a space for improvements such as: - Add support for the new pass manager - Add support for metadata other than DILocations and DISubprograms [0] https://groups.google.com/forum/#!msg/llvm-dev/QOyF-38YPlE/G213uiuwCAAJ [1] https://github.com/djolertrk/llvm-di-checker Differential Revision: https://reviews.llvm.org/D82545 |
