INITIALIZATION STATUS OF A REGISTER EMPLOYED AS A POINTER

摘要

Initialization status of a register to be used as a pointer to a reference data structure is used to determine how a stub is to be generated to access the reference data structure. The register is one type of pointer configuration to be used to access the reference data structure, which is used to resolve a symbol associated with a function of a program. An indication is obtained as to whether the register has been initialized with a reference data structure pointer. Based on obtaining the indication, a stub is generated that is to be used to access the function. The generating depends on whether the register has been initialized. If the register has not been initialized, then the stub is generated to include another type of pointer configuration to be used to access the reference data structure.

1. A computer-implemented method of facilitating processing within a computing environment, the computer-implemented method comprising:
obtaining, by a processor, an indication of whether a 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 based on obtaining the indication, generating a stub to be used to access the function, the generating depending on whether the indication indicates the register has been initialized, wherein based on the indication indicating the register has not been initialized, the generating 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.
