Windows 8 and 10 performs some address space randomization (DLL loading and memory allocations), probably for security reasons. This makes it more likely to that an inter-DLL function call is located more than 2GB away. 32-bit PC relative relocation cannot be used to perform an inter-DLL function call (unless going through the PLT). This is true for all memory models.


Is there any documentation that Windows 8 and 10 indeed use large code model?
