[PATCH] D40778: [DebugIR] Revive the Debug IR pass. [Added llvm-commits]

[Siddharth via Phabricator via llvm-commits]

bollu created this revision.
bollu added a project: debug-info.
Herald added subscribers: JDevlieghere, aprantl, mgorny.

Re-submitting this patch since I had not added llvm-commits previously. Old patch: https://reviews.llvm.org/D40207

This is a revival of the old DebugIR pass <https://reviews.llvm.org/rL222945>.

This pass strips away old debug info, and inserts new debug info that provides LLVM IR leveldebugging in a debugger.

I do not fully understand the debug infrastructure of LLVM, so reviews will be much appreciated!
