◆ createFromBuffer()

ErrorOr< std::unique_ptr< LTOModule > > LTOModule::createFromBuffer ( LLVMContext &  Context,
const void *  mem,
size_t  length,
const TargetOptions &  options,
StringRef  path = "" 
)

◆ createFromFile()

ErrorOr< std::unique_ptr< LTOModule > > LTOModule::createFromFile ( LLVMContext &  Context,
StringRef  path,
const TargetOptions &  options 
)
static

Create an LTOModule.

N.B. These methods take ownership of the buffer. The caller must have initialized the Targets, the TargetMCs, the AsmPrinters, and the AsmParsers by calling:

InitializeAllTargets(); InitializeAllTargetMCs(); InitializeAllAsmPrinters(); InitializeAllAsmParsers();
