Abstract: A method includes, in a processor, processing a sequence of pre-compiled instructions by an instruction pipeline of the processor. A first block of instructions is identified in the instructions flowing via the pipeline. The first block includes a conditional branch instruction that conditionally diverges execution of the instructions into at least first and second flow-control traces that differ from one another in multiple instructions and converge at a given instruction that is again common to the first and second flow-control traces. A second block of instructions, which is logically equivalent to the first block but replaces the first and second flow-control traces by a single flow-control trace, is created by the processor at runtime. The pipeline is caused to execute the second block instead of the first block.

Abstract: A method includes retrieving to a pipeline of a processor first instructions of program code from a first region in the program code. Before fully determining a flow-control path, which is to be traversed within the first region until exit from the first region, a beginning of a second region in the code that is to be processed following the first region is predicted, and second instructions begin to be retrieved to the pipeline from the second region. The retrieved first instructions and second instructions are processed by the pipeline.

Abstract: Method(s) for up/down fusion and/or pseudo-fusion of micro-operations are performed in a hardware processor configured to execute program code. A mergeable pair of micro-operations is identified in a sequence of micro-operations of the program code. The pair of micro-operations includes a first micro-operation for performing a first function and a non-consecutive second micro-operation for performing a second function. The first micro-operation precedes the second micro-operation in the sequence of micro-operations being processed. The first micro-operation is merged into the second micro-operation to create a third micro-operation which performs both the first function and the second function. In up/down fusion the third micro-operation is dispatched instead of the first micro-operation or instead of the second micro-operation, based on whether fuse-up or fuse-down is performed.

Abstract: A method includes, in a processor (20) that processes instructions of program code, processing a first segment of the instructions. One or more destination registers are identified in the first segment using an approximate specification of register access by the instructions. Respective values of the destination registers are made available to a second segment of the instructions only upon verifying that the values are valid for readout by the second segment in accordance with the approximate specification. The second segment is processed at least partially in parallel with processing of the first segment, using the values made available from the first segment.

Abstract: A method includes, in a processor having a pipeline, fetching instructions of program code at run-time, in an order that is different from an order-of-appearance of the instructions in the program code. The instructions are divided into segments having segment identifiers (IDs). An event, which warrants flushing of instructions starting from an instruction belonging to a segment, is detected. In response to the event, at least some of the instructions in the segment that are subsequent to the instruction, and at least some of the instructions in one or more subsequent segments that are subsequent to the segment, are flushed from the pipeline based on the segment IDs.
