Processor testing

A system comprising:

• a computer readable storage medium storing instructions for processor testing;
• and
• a processor, according to the instructions, configured to:
• generate a set of test instructions having a first portion and a second portion;
• randomly generate a first branch instruction for the first portion, the first branch instruction branching to a respective instruction in a second portion by a branching location offset;
• randomly generate a second branch instruction for the second portion, the second branch instruction branching to a respective instruction in the first portion by the branching location offset;
• determine whether to add another instruction to the set of test instructions;
• responsive to determining to add an other instruction to the set of test instructions, increment a value of the branching location offset by a predetermined amount;
• and
• write the instructions to the computer readable storage medium.

A computer program product for generating test instructions for a processor, the computer program product comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising computer readable program code configured to:
• generate a set of test instructions having a first portion and a second portion;
• randomly generate a first branch instruction for the first portion, the first branch instruction branching to a respective instruction in a second portion by a branching location offset;
• randomly generate a second branch instruction for the second portion, the second branch instruction branching to a respective instruction in the first portion by the branching location offset;
• determine whether to add another instruction to the set of test instructions;
• and
• responsive to determining to add an other instruction to the set of test instructions, increment a value of the branching location offset by a predetermined amount.
