Constructor & Destructor Documentation

DumpObjects()

llvm::orc::DumpObjects::DumpObjects	(	std::string	DumpDir = "",
		std::string	IdentifierOverride = ""
	)

Construct a DumpObjects transform that will dump objects to disk.

Parameters

DumpDir

specifies the path to write dumped objects to. DumpDir may be empty, in which case files will be dumped to the working directory. If DumpDir is non-empty then any trailing separators will be discarded.

IdentifierOverride

specifies a file name stem to use when dumping objects. If empty, each MemoryBuffer's identifier will be used (with a .o suffix added if not already present). If an identifier override is supplied it will be used instead (since all buffers will use the same identifier, the resulting files will be named <ident>.o, <ident>.2.o, <ident>.3.o, and so on). IdentifierOverride should not contain an extension, as a .o suffix will be added by DumpObjects.

Discard any trailing separators.
