👉 Compile-time IOR (Inter-Object Relocation) is a feature in some programming languages that allows the compiler to automatically adjust memory addresses when objects are moved within a program. This process involves analyzing the code to determine where objects are relocated and then updating all references to those objects with new addresses, ensuring that the program's logic remains consistent without manual intervention. By performing these relocations during compilation, compile-time IOR reduces runtime overhead and potential errors associated with address calculations, leading to more efficient and reliable code execution.
