Linker specifies the relocating bits used by relocating loader
Relocating bits in a relocating loader are specified by the linker. The linker is responsible for combining multiple object files into a single executable file.

Explanation:

Relocating Loader:
A relocating loader is a type of loader that loads a program into memory for execution and adjusts the program's object code so that it can be executed from a different memory location than the one originally specified during compilation. This process involves relocating bits of the program to accommodate the memory layout of the target system.

Linker:
The linker is a program that combines multiple object files generated by the assembler into a single executable file. It resolves external references, assigns final memory addresses to program variables and functions, and generates relocation information that specifies which parts of the program need to be relocated by the loader.

Relocation Bits:
Relocation bits are special markers embedded in the object code by the linker to indicate which parts of the program need to be relocated by the loader. These bits help the loader adjust memory addresses and references so that the program can run correctly in the target system.

Role of Linker in Specifying Relocating Bits:
The linker is responsible for generating relocation information based on the memory layout of the target system and the dependencies between different object files. It determines the memory addresses that need to be adjusted during loading and inserts relocation bits into the object code to guide the relocating loader.
In conclusion, the linker plays a crucial role in specifying the relocating bits used by a relocating loader. It generates relocation information and embeds relocation bits in the object code to facilitate the correct execution of the program in different memory locations.
