Extended Description

Running llc test.ll yields an assertion failure in DwarfDebug.cpp. I have run bugpoint to reduce the testcase, but it doesn't help much because the bug is in the metadata.

The assertion is:
llc: llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp:299: llvm::DIE* llvm::DwarfDebug::updateSubprogramScopeDIE(const llvm::MDNode*): Assertion `SPDie && "Unable to find subprogram DIE!"' failed.

Can you regenerate llvm byte code file, we have updated recently how debug info is encoded in LLVM IR ? Thanks.

I rebuilt the test case from source with clang and LLVM revision 139148. It appears to work correctly now, so I am marking the bug fixed. Thanks.
