◆ DWARFToGSYMFileIndex()

uint32_t llvm::gsym::CUInfo::DWARFToGSYMFileIndex	(	GsymCreator &	Gsym,
		uint32_t	DwarfFileIdx
	)

inline

Convert a DWARF compile unit file index into a GSYM global file index.

Each compile unit in DWARF has its own file table in the line table prologue. GSYM has a single large file table that applies to all files from all of the info in a GSYM file. This function converts between the two and caches and DWARF CU file index that has already been converted so the first client that asks for a compile unit file index will end up doing the conversion, and subsequent clients will get the cached GSYM index.

◆ isHighestAddress()

bool llvm::gsym::CUInfo::isHighestAddress ( uint64_t Addr ) const

inline

Return true if Addr is the highest address for a given compile unit.

The highest address is encoded as -1, of all ones in the address. These high addresses are used by some linkers to indicate that a function has been dead stripped or didn't end up in the linked executable.
