Simplify cfg inserts a call to trap when unreachable code is detected. Assign DebugLoc to this new trap instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130315 91177308-0d34-0410-b5e6-96231b3b80d8

Debug Info Verifier: verify SPs in llvm.dbg.sp. Also always add DIType, DISubprogram and DIGlobalVariable to the list in DebugInfoFinder without checking them, so we can verify them later on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187285 91177308-0d34-0410-b5e6-96231b3b80d8

Debug Info: update testing cases to specify the debug info version number. We are going to drop debug info without a version number or with a different version number, to make sure we don't crash when we see bitcode files with different debug info metadata format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195504 91177308-0d34-0410-b5e6-96231b3b80d8

Revert "Revert "DI: Fold constant arguments into a single MDString"" This reverts commit r218918, effectively reapplying r218914 after fixing an Ocaml bindings test and an Asan crash. The root cause of the latter was a tightened-up check in `DILexicalBlock::Verify()`, so I'll file a PR to investigate who requires the loose check (and why). Original commit message follows. -- This patch addresses the first stage of PR17891 by folding constant arguments together into a single MDString. Integers are stringified and a `\0` character is used as a separator. Part of PR17891. Note: I've attached my testcases upgrade scripts to the PR. If I've just broken your out-of-tree testcases, they might help. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219010 91177308-0d34-0410-b5e6-96231b3b80d8
