[PATCH] D45024: [DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label.

[Hsiangkai Wang via Phabricator via llvm-commits]

HsiangKai updated this revision to Diff 142000.
HsiangKai added a comment.

Add DILabel list to DISubprogram. The new DISubprogram will be

DISubprogram(..., variables: !7, labels: !8)

To maintain all local entities of the function in one list is not trivial modification. I think it should not relate to label debugging. The refactoring of these lists into one should be another patch.

So, to enable label debugging, I use a separate list to maintain labels in the function. I add a test case in https://reviews.llvm.org/D45045 under Clang repo.
