David Blaikie a42211335a DebugInfo: Ensure that all debug location scope chains from instructions within a function, lead to the function itself. ... Originally committed in r211723, reverted in r211724 due to failure cases found and fixed (ArgumentPromotion: r211872, Inlining: r212065), committed again in r212085 and reverted again in r212089 after fixing some other cases, such as debug info subprogram lists not keeping track of the function they represent (r212128) and then short-circuiting things like LiveDebugVariables that build LexicalScopes for functions that might not have full debug info. And again, I believe the invariant actually holds for some reasonable amount of code (but I'll keep an eye on the buildbots and see what happens... ). Original commit message: PR20038: DebugInfo: Inlined call sites where the caller has debug info but the call itself has no debug location. This situation does bad things when inlined, so I've fixed Clang not to produce inlinable call sites without locations when the caller has debug info (in the one case where I could find that this occurred). This updates the PR20038 test case to be what clang now produces, and readds the assertion that had to be removed due to this bug. I've also beefed up the debug info verifier to help diagnose these issues in the future, and I hope to add checks to the inliner to just assert-fail if it encounters this situation. If, in the future, we decide we have to cope with this situation, the right thing to do is probably to just remove all the DebugLocs from the inlined instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212205 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-02 18:32:05 +00:00
