Techniques for performance analysis of processor instruction execution

A method, comprising:

• accessing a program for performance analysis, the program comprising at least one producer instruction and at least one consumer instruction for the at least one producer instruction;
• and
• generating an analysis program based on the program, the analysis program comprising a stall time instruction set to determine a stall time of the at least one producer instruction, the stall time instruction set comprising a first time stamp instruction immediately preceding the at least one consumer instruction, a second time stamp instruction immediately following the at least one consumer instruction, and a stall time instruction to determine the stall time as the difference between the second time stamp and the first time stamp.

A non-transitory computer-readable storage medium that stores computer-executable instructions for execution by processing circuitry of a computing device to generate invariant-reference compressed data, the computer-executable instructions, when executed, to cause the computing device to:

• access a program for performance analysis, the program comprising at least one producer instruction and at least one consumer instruction for the at least one producer instruction;
• and
• generate an analysis program based on the program, the analysis program comprising a stall time instruction set to determine a stall time of the at least one producer instruction, the stall time instruction set comprising a first time stamp instruction immediately preceding the at least one consumer instruction, a second time stamp instruction immediately following the at least one consumer instruction, and a stall time instruction to determine the stall time as the difference between the second time stamp and the first time stamp.
