◆ loadModuleForTwoRounds()

std::unique_ptr<Module > llvm::cgdata::loadModuleForTwoRounds	(	BitcodeModule &	OrigModule,
		unsigned	Task,
		LLVMContext &	Context,
		ArrayRef<StringRef >	IRFiles
	)

Load the optimized bitcode module for the second codegen round.

OrigModule is the original bitcode module.Task identifies the partition number in the parallel code generation process.Context provides the environment settings for module operations.IRFiles contains optimized bitcode module files needed for loading.

Returns: A unique_ptr to the loadedModule, or nullptr if loading fails.

)

Merge the codegen data from the scratch objectsObjectFiles from the first codegen round.

Returns: the combined hash of the merged codegen data.

◆ saveModuleForTwoRounds()

void llvm::cgdata::saveModuleForTwoRounds	(	const Module &	TheModule,
		unsigned	Task,
		AddStreamFn	AddStream
	)

SaveTheModule before the first codegen round.

Task represents the partition number in the parallel code generation process.AddStream is the callback used to add the serialized module to the stream.
