Detailed Description

Dumps symbol tables from LinkGraphs to enable backtrace symbolication.

This plugin appends symbol information to a file in the following format: "<link graph name>" <address> <symbol name> <address> <symbol name> ...

Where addresses are in hexadecimal and symbol names are for defined symbols.

SymbolTableDumpPlugin() [1/3]

llvm::orc::SymbolTableDumpPlugin::SymbolTableDumpPlugin	(	StringRef	Path,
		std::error_code &	EC )

Create a SymbolTableDumpPlugin.

The resulting object is in an invalid state if, upon return, EC != std::error_code(). Prefer SymbolTableDumpPlugin::Create.
