Member Enumeration Documentation

Mode

enum class llvm::orc::Mangler::Mode

strong

The linker name-mangling scheme for a target, determined by its object format.

This captures the platform decoration applied to symbol names (e.g. a leading '_' on MachO), independently of any ExecutionSession.

Member Function Documentation

mangledCopy()

std::string llvm::orc::Mangler::mangledCopy ( const SymbolNameSpec & Name ) const

inline

Construct a mangled version of the given name as a std::string.

This always produces a copy, even for no-op manglings. Prefer withMangledNameDo in any performance-sensitive context.

Definition at line 72 of file Mangler.h.

References llvm::StringRef::str(), and withMangledNameDo().

withMangledNameDo()

template<typename HandlerFn>

decltype(auto) llvm::orc::Mangler::withMangledNameDo ( HandlerFn && H, const SymbolNameSpec & NameSpec ) const

inline

Calls the given callback with the mangled version of NameSpec as a StringRef.

The mangled name is only valid for the duration of the callback and must not escape. This allows withMangledNameDo to avoid allocations when mangling is a no-op.
