Loader:

Relocating an executable (or DLL) module is an absolutely horrible process, and you should take measures to avoid it. Let's see why. Suppose that the loader relocates the second DLL to address 0x. In that case, the code that changes the g_x4. Describe the design of a Relocating loader.What is the advantage of a Relocating loader over Absolute loader?Discuss. [10][ Loader] 5. Describe the various Loading schemes with suitable example from each.[10][Loader] 6. Describe the databases used in. 7. · The output of a relocating loader is the program and information about all other programs it references. In addition, there is information (relocation information) as to location in this program that must be change if it is to be loaded in an arbitrary location in memory. In ….
