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

The test that was failing is now forced to use the old PM.
