From b981832951108f151136227b6df3dfdd410e4705 Mon Sep 17 00:00:00 2001 From: Frederic Riss Date: Sat, 28 Feb 2015 00:29:07 +0000 Subject: [PATCH] [dsymutil] Add a LinkOptions struct to pass to the DwarfLinker. NFC. The only option we have to pass down currently is verbosity, but there are more to come. llvm-svn: 230823 --- llvm/tools/dsymutil/DwarfLinker.cpp | 26 ++++++++++++++------------ llvm/tools/dsymutil/dsymutil.cpp | 5 ++++- llvm/tools/dsymutil/dsymutil.h | 9 ++++++++- 3 files changed, 26 insertions(+), 14 deletions(-) diff --git a/llvm/tools/dsymutil/DwarfLinker.cpp b/llvm/tools/dsymutil/DwarfLinker.cpp index 71af214..e44797d 100644 --- a/llvm/tools/dsymutil/DwarfLinker.cpp +++ b/llvm/tools/dsymutil/DwarfLinker.cpp @@ -71,8 +71,9 @@ private: /// first step when we start processing a DebugMapObject. class DwarfLinker { public: - DwarfLinker(StringRef OutputFilename, bool Verbose) - : OutputFilename(OutputFilename), Verbose(Verbose), BinHolder(Verbose) {} + DwarfLinker(StringRef OutputFilename, const LinkOptions &Options) + : OutputFilename(OutputFilename), Options(Options), + BinHolder(Options.Verbose) {} /// \brief Link the contents of the DebugMap. bool link(const DebugMap &); @@ -181,7 +182,7 @@ private: private: std::string OutputFilename; - bool Verbose; + LinkOptions Options; BinaryHolder BinHolder; /// The units of the current debug map object. @@ -229,7 +230,7 @@ void DwarfLinker::reportWarning(const Twine &Warning, const DWARFUnit *Unit, Context = CurrentDebugObject->getObjectFilename(); warn(Warning, Context); - if (!Verbose || !DIE) + if (!Options.Verbose || !DIE) return; errs() << " in DIE:\n"; @@ -383,7 +384,7 @@ bool DwarfLinker::hasValidRelocation(uint32_t StartOffset, uint32_t EndOffset, return false; const auto &ValidReloc = ValidRelocs[NextValidReloc++]; - if (Verbose) + if (Options.Verbose) outs() << "Found valid debug map entry: " << ValidReloc.Mapping->getKey() << " " << format("\t%016" PRIx64 " => %016" PRIx64, ValidReloc.Mapping->getValue().ObjectAddress, @@ -447,7 +448,7 @@ unsigned DwarfLinker::shouldKeepVariableDIE( (Flags & TF_InFunctionScope)) return Flags; - if (Verbose) + if (Options.Verbose) DIE.dump(outs(), const_cast(&OrigUnit), 0, 8 /* Indent */); return Flags | TF_Keep; @@ -479,7 +480,7 @@ unsigned DwarfLinker::shouldKeepSubprogramDIE( !hasValidRelocation(LowPcOffset, LowPcEndOffset, MyInfo)) return Flags; - if (Verbose) + if (Options.Verbose) DIE.dump(outs(), const_cast(&OrigUnit), 0, 8 /* Indent */); return Flags | TF_Keep; @@ -616,7 +617,7 @@ bool DwarfLinker::link(const DebugMap &Map) { for (const auto &Obj : Map.objects()) { CurrentDebugObject = Obj.get(); - if (Verbose) + if (Options.Verbose) outs() << "DEBUG MAP OBJECT: " << Obj->getObjectFilename() << "\n"; auto ErrOrObj = BinHolder.GetObjectFile(Obj->getObjectFilename()); if (std::error_code EC = ErrOrObj.getError()) { @@ -626,7 +627,7 @@ bool DwarfLinker::link(const DebugMap &Map) { // Look for relocations that correspond to debug map entries. if (!findValidRelocsInDebugInfo(*ErrOrObj, *Obj)) { - if (Verbose) + if (Options.Verbose) outs() << "No valid relocations found.
