Summary: We are inserting both Scope and SP into the Seen map and check whether it was already there in which case we skip the validation (the idea being that we already checked this Subprogram before). However, if (Scope == SP) as MDNodes, then inserting the Scope, will trigger the Seen check causing us to incorrectly not validate this !dbg attachment. Fix this by not performing the SP Seen check if Scope == SP Reviewers: pcc, dexonsmith, dblaikie Subscribers: dblaikie, llvm-commits Differential Revision: http://reviews.llvm.org/D14697 llvm-svn: 254887
