Specifically, the compiler or linker assigns the address of the instruction processing function to a specific register, such as the program entry address or start address. When the program starts, the entry macro calls the corresponding instruction processing function according to the address in the register. This method enables the program to execute the instruction processing functions in the planned order at startup, thus achieving control over the program. Different programming languages and compilers may have different implementations."}]}],"pr":"2de9a49a28918333e514179145a3d2da5bc50d99f069248d6d62958a2cde59f5"}
