C++ (Cpp) transitionState Examples

Example #1

File: MachOObject.cpp Project: 010001111/darling

void MachOObject::load()
{
	if (isLoaded())
		throw std::logic_error("Module already loaded");
	if (strcmp(m_file->platform(), ARCH_NAME) != 0)
	{
		std::stringstream ss;
		ss << "This version of Darling dyld cannot load binaries for " << m_file->platform() << ".";
		throw std::runtime_error(ss.str());
	}
	
	loadSegments();
	transitionState(dyld_image_state_mapped);
	
	if (m_slide > 0)
		rebase();
	transitionState(dyld_image_state_rebased);
	
	readSymbols();
	readExports();

	MachOMgr::instance()->add(this, isMainModule());

	loadDependencies();
	
	performRelocations();
	performBinds();
	transitionState(dyld_image_state_bound);
	transitionState(dyld_image_state_dependents_initialized);
	
	// registerEHSection();
	
	if (isMainModule())
		fillInProgramVars();
	fillInDyldData();
	
	setInitialSegmentProtection();
	setupTLS();
	
	MachOMgr::instance()->notifyAdd(this);
	runInitializers();

	transitionState(dyld_image_state_initialized);
	
	m_file->closeFd();
	
	if (MachOMgr::instance()->printLibraries())
		std::cerr << "dyld: Loaded " << this->path() << std::endl;
}

Example #2

}

Example #3

File: MachOObject.cpp Project: 010001111/darling
