Before we start to rely on valid `!dbg` attachments, add a check to the verifier that `@llvm.dbg.*` intrinsics always have one. Also check that the `scope:` fields point at the same `MDSubprogram`. This is in the context of PR22778. The check that the `inlinedAt:` fields agree has baked for a while (since r234021), so I'll kill [1] the `MDLocalVariable::getInlinedAt()` field soon. [1]: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150330/269387.html Unfortunately, that means it's impossible to keep the current `Verifier` checks, which rely on comparing `inlinedAt:` fields. We'll be able to keep the checks I'm adding here. If this breaks your out-of-tree testcases, the upgrade script (add-dbg-to-intrinsics.sh) attached to PR22778 that I used for r235040 might fix them for you. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235048 91177308-0d34-0410-b5e6-96231b3b80d8
This directory contains testcases that the verifier is supposed to detect as malformed LLVM code. Testcases for situations that the verifier incorrectly identifies as malformed should go in the test/Assembler directory.
