Single instruction register providing multiple instruction operands

A computer system comprising:

• at least one computing device;
• a set of one or more computer-readable storage media;
• and
• program instructions, collectively stored in the set of one or more computer-readable storage media, for causing the at least one computing device to perform computer operations including:
• executing an instruction within a computing environment, the executing the instruction including:
• obtaining a plurality of operands of the instruction, the obtaining the plurality of operands including:
• retrieving from a register of the instruction multiple designations of multiple operand locations, the register being a single register of the instruction, and wherein the multiple operand locations provided by the single register are used to provide multiple operands of the plurality of operands of the instruction;
• determining from the multiple operand locations the multiple operands of the instruction;
• and
• performing one or more operations of the instruction using one or more operands of the plurality of operands of the instruction to obtain a result of the instruction.

A computer-implemented method comprising:

• executing an instruction within a computing environment, the executing the instruction including:
• obtaining a plurality of operands of the instruction, the obtaining the plurality of operands including:
• retrieving from a register of the instruction multiple designations of multiple operand locations, the register being a single register of the instruction, and wherein the multiple operand locations provided by the single register are used to provide multiple operands of the plurality of operands of the instruction;
• determining from the multiple operand locations the multiple operands of the instruction;
• and
• performing one or more operations of the instruction using one or more operands of the plurality of operands of the instruction to obtain a result of the instruction.

A computer program product comprising:

• a set of one or more computer-readable storage media;
• and
• program instructions, collectively stored in the set of one or more computer-readable storage media, for causing at least one computing device to perform computer operations including:
• executing an instruction within a computing environment, the executing the instruction including:
• retrieving from a single register of the instruction at least one base-displacement pair of multiple base-displacement pairs located within the single register, the at least one base-displacement pair to be used to provide at least one operand of the instruction;
• determining from the at least one base-displacement pair the at least one operand of the instruction;
• and
• performing one or more operations of the instruction using, at least, the at least one operand of the instruction to obtain a result of the instruction.
