StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50
An ExecutionSession represents a running JIT program.
Definition: Core.h:1373

static void add(ExecutionSession &ES, const ManglingOptions &MO, ArrayRef< GlobalValue * > GVs, SymbolFlagsMap &SymbolFlags, SymbolNameToDefinitionMap *SymbolToDefinition=nullptr)
Add mangled symbols for the given GlobalValues to SymbolFlags.
