[PATCH] D53736: [BTF] Add BTF DebugInfo

[Yonghong Song via Phabricator via llvm-commits]

yonghong-song updated this revision to Diff 171730.
yonghong-song added a comment.

kernel BTF verifier requires if a FUNC kind is a subprogram, all its arguments must be valid identifier.
Using SP RetainedNodes instead DbgValues so we can get all argument local variables even if they
are not used in the function body. Added a test case to test such a scenario.
