This is a regression caused by r106792 and caught by gdb testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107430 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/DwarfDebug.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp index 50c0feac091..5343adaa7a2 100644 --- a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp @@ -2690,10 +2690,12 @@ void DwarfDebug::beginFunction(const MachineFunction *MF) { DIVariable DV(MI->getOperand(MI->getNumOperands() - 1).getMetadata()); if (!DV.Verify()) continue; // If DBG_VALUE is for a local variable then it needs a label. - if (DV.getTag() != dwarf::DW_TAG_arg_variable) + if (DV.getTag() != dwarf::DW_TAG_arg_variable + && isDbgValueInUndefinedReg(MI) == false) InsnNeedsLabel.insert(MI); // DBG_VALUE for inlined functions argument needs a label. - else if (!DISubprogram(DV.getContext()).describes(MF->getFunction())) + else if (!DISubprogram(getDISubprogram(DV.getContext())). + describes(MF->getFunction())) InsnNeedsLabel.insert(MI); // DBG_VALUE indicating argument location change needs a label. else if (isDbgValueInUndefinedReg(MI) == false && !ProcessedArgs.insert(DV)) -- 2.11.0
