Function Documentation

static void copyGVAttributes	(	GlobalValue *	DestGV,
		const GlobalValue *	SrcGV
	)		[static]

copyGVAttributes - copy additional attributes (those not needed to construct a GlobalValue) from the SrcGV to the DestGV.

Definition at line 468 of file LinkModules.cpp.

static void forceRenaming	(	GlobalValue *	GV,
		StringRef	Name
	)		[static]

forceRenaming - The LLVM SymbolTable class autorenames globals that conflict in the symbol table. This is good for all clients except for us. Go through the trouble to force this back.
