From 01079311e153dae59a38aa0cdf5332eb3e410abf Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Wed, 23 Mar 2011 18:37:30 +0000 Subject: [PATCH] Don't coalesce identical DBG_VALUE instructions prematurely. Each of these instructions may have a RegsClobberInsn entry that can't be ignored. Consecutive ranges are coalesced later when DwarfDebug::emitDebugLoc merges entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128155 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/DwarfDebug.cpp | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp index 7c50b1e4607..58d51ea2ac8 100644 --- a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp @@ -2419,14 +2419,12 @@ DwarfDebug::collectVariableInfo(const MachineFunction *MF, if (Processed.count(DV) != 0) continue; - const MachineInstr *PrevMI = MInsn; for (SmallVector::iterator MI = I+1, ME = DbgValues.end(); MI != ME; ++MI) { const MDNode *Var = (*MI)->getOperand((*MI)->getNumOperands()-1).getMetadata(); - if (Var == DV && !PrevMI->isIdenticalTo(*MI)) + if (Var == DV) MultipleValues.push_back(*MI); - PrevMI = *MI; } DbgScope *Scope = NULL; -- 2.34.1
