Initialization status of a register employed as a pointer

A computer system for facilitating processing within a computing environment, said computer system comprising:

• a memory;
• and
• a processor in communications with the memory, wherein the computer system is configured to perform a method, the method comprising:
• obtaining, by the processor, initialization status of a register, the initialization status indicating whether the register has been initialized with a reference data structure pointer, the register being one type of pointer configuration to be used to access a reference data structure to be used to resolve a symbol associated with a function of a program, and wherein the initialization status is to be used in generating a stub to be used to access the function, and
• based on obtaining the initialization status of the register, generating the stub to be used to access the function, the generating depending on whether the initialization status indicates the register has been initialized, wherein:
• based on the initialization status indicating the register has been initialized with the reference data structure pointer, the generating the stub comprises generating the stub using the register;
• and
• based on the initialization status indicating the register has not been initialized with the reference data structure pointer, the generating the stub comprises generating the stub to include another type of pointer configuration to be used to access the reference data structure, the other type of pointer configuration being different from the one type of pointer configuration in that the stub is generated without referencing the register in the stub.
