Functions
static uint64_t	llvm::getDebugInfoSize (DWARFContext &Dwarf)
	Compute the total size of the debug info.
static CompileUnit *	llvm::getUnitForOffset (const UnitListTy &Units, uint64_t Offset)
	Similar to DWARFUnitSection::getUnitForOffset(), but returning our CompileUnit object instead.
static bool	llvm::isODRAttribute (uint16_t Attr)
static bool	llvm::isTypeTag (uint16_t Tag)
static void	llvm::resolveRelativeObjectPath (SmallVectorImpl< char > &Buf, DWARFDie CU)
	Resolve the relative path to a build artifact referenced by DWARF by applying DW_AT_comp_dir.
static void	llvm::analyzeImportedModule (const DWARFDie &DIE, CompileUnit &CU, DWARFLinkerBase::SwiftInterfacesMapTy *ParseableSwiftInterfaces, std::function< void(const Twine &, const DWARFDie &)> ReportWarning)
	Collect references to parseable Swift interfaces in imported DW_TAG_module blocks.
static bool	llvm::updatePruning (const DWARFDie &Die, CompileUnit &CU, uint64_t ModulesEndOffset)
static void	llvm::updateChildPruning (const DWARFDie &Die, CompileUnit &CU, CompileUnit::DIEInfo &ChildInfo)
static void	llvm::analyzeContextInfo (const DWARFDie &DIE, unsigned ParentIdx, CompileUnit &CU, DeclContext *CurrentDeclContext, DeclContextTree &Contexts, uint64_t ModulesEndOffset, DWARFLinkerBase::SwiftInterfacesMapTy *ParseableSwiftInterfaces, std::function< void(const Twine &, const DWARFDie &)> ReportWarning)
	Recursive helper to build the global DeclContext information and gather the child->parent relationships in the original compile unit.
static bool	llvm::dieNeedsChildrenToBeMeaningful (uint32_t Tag)
static bool	llvm::isTlsAddressCode (uint8_t DW_OP_Code)
static void	llvm::updateChildIncompleteness (const DWARFDie &Die, CompileUnit &CU, CompileUnit::DIEInfo &ChildInfo)
	Helper that updates the completeness of the current DIE based on the completeness of one of its children.
static void	llvm::updateRefIncompleteness (const DWARFDie &Die, CompileUnit &CU, CompileUnit::DIEInfo &RefInfo)
	Helper that updates the completeness of the current DIE based on the completeness of the DIEs it references.
static bool	llvm::isODRCanonicalCandidate (const DWARFDie &Die, CompileUnit &CU)
static void	llvm::verifyKeepChain (CompileUnit &CU)
	Verify the keep chain by looking for DIEs that are kept but who's parent isn't.
static bool	llvm::shouldSkipAttribute (bool Update, DWARFAbbreviationDeclaration::AttributeSpec AttrSpec, bool SkipPC)
static void	llvm::patchAddrBase (DIE &Die, DIEInteger Offset)
static void	llvm::insertLineSequence (std::vector< DWARFDebugLine::Row > &Seq, std::vector< DWARFDebugLine::Row > &Rows)
	Insert the new line info sequence Seq into the current set of already linked line info Rows.
static void	llvm::patchStmtList (DIE &Die, DIEInteger Offset)
static uint64_t	llvm::getDwoId (const DWARFDie &CUDie)
