摘要
Embodiments include methods, computer systems and computer program products for performing superscalar out-of-order processing in software in a computer system. Aspects include: loading opcodes into an analysis thread of the computer system, analyzing opcodes to identify certain non-independent opcode snippets, distributing non-independent opcode snippets to separate threads of computer system, instructing each of separate threads to execute each of non-independent opcode snippets, respectively, and collecting results of executions of each of separate threads by a consolidation thread. In exemplary embodiments, analyzing may include analyzing the opcodes using arbitrarily large variable size instruction windows to identify the non-independent opcode snippets, and distributing may include distributing opcode snippets: to a thread of same ISA, and to a code morphing thread when the opcode snippets need to be executed in threads of different ISA and then distributing the opcode snippets to the threads of different ISA by the code morphing thread.
