From 393a46deb66be6885fd064a38e650bed859af5a1 Mon Sep 17 00:00:00 2001 From: Devang Patel Date: Tue, 6 Oct 2009 01:50:42 +0000 Subject: Add utility routine to set begin and end labels for DbgScopes. This will be used by processDebugLoc(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83361 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/DwarfDebug.cpp | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'lib/CodeGen/AsmPrinter/DwarfDebug.cpp') diff --git a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp index 89995af..c727465 100644 --- a/lib/CodeGen/AsmPrinter/DwarfDebug.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfDebug.cpp @@ -1796,6 +1796,30 @@ void DwarfDebug::CollectVariableInfo() { } } +/// SetDbgScopeBeginLabels - Update DbgScope begin labels for the scopes that +/// start with this machine instruction. +void DwarfDebug::SetDbgScopeBeginLabels(const MachineInstr *MI, unsigned Label) { + InsnToDbgScopeMapTy::iterator I = DbgScopeBeginMap.find(MI); + if (I == DbgScopeBeginMap.end()) + return; + SmallVector &SD = I->second; + for (SmallVector::iterator SDI = SD.begin(), SDE = SD.end(); + SDI != SDE; ++SDI) + (*SDI)->setStartLabelID(Label); +} + +/// SetDbgScopeEndLabels - Update DbgScope end labels for the scopes that +/// end with this machine instruction. +void DwarfDebug::SetDbgScopeEndLabels(const MachineInstr *MI, unsigned Label) { + InsnToDbgScopeMapTy::iterator I = DbgScopeEndMap.find(MI); + if (I == DbgScopeBeginMap.end()) + return; + SmallVector &SD = I->second; + for (SmallVector::iterator SDI = SD.begin(), SDE = SD.end(); + SDI != SDE; ++SDI) + (*SDI)->setEndLabelID(Label); +} + /// ExtractScopeInformation - Scan machine instructions in this function /// and collect DbgScopes.
