摘要： A method and apparatus for optimizing a sequence of operations adapted for execution by a processor is disclosed to include locating an operation, if any, that is next within the sequence of operations and setting a current operation to be that operation. The current operation is processed as follows: a) de-activating, if not already de-activated, a consumed indicator associated with the current operation; and b) when the current operation is of the producer type, then activating, if not already activated, a producer indicator associated with the current operation, and locating a first set of operations, if any, that i) are earlier in the sequence of operations than the current operation, ii) have their associated producer indicator activated, and iii) have their associated consumed indicator de-activated, and then de-activating the producer indicator associated with each operation in the first set. When the current operation is of the consumer type, then locating a second set of operations, if any, that are earlier in the sequence of operations than the current operation, and then activating, if not already activated, the consumed indicator associated with each operation in the second set.

摘要： A method of handling a trace to be aborted includes receiving an indication of a trace to be aborted and an indication of an abort reason corresponding to an execution of the trace to be aborted. The trace to be aborted has a trace type associated therewith and includes a sequence of the operations, and represents a sequence of at least two of the instructions. The method further includes identifying a corrective action based at least in part on the type of the trace to be aborted and on the abort reason, not taking into account a correspondence between the at least one operation that caused the execution to be aborted and the at least one instruction that the at least one operation at least in part represents. A next trace and its trace type is determined for execution, where the determining is based on the trace to be aborted and on the corrective action.

摘要： A method and system for promoting traces in an instruction processing circuit is disclosed. The method and system comprises determining if a current trace is promotable; and adding the current trace to a sequence buffer if the current trace is promotable. The current trace is marked as promoted and the current trace is marked as a first trace of a multi-block trace. The method and system includes determining if a next trace is promotable; adding the next trace to the sequence buffer if the next trace is promotable; and repeating the above until the next trace is not promotable and then adding the next trace to the sequence buffer if the next trace is not promotable.

摘要： A method and apparatus for optimizing a sequence of operations adapted for execution by a processor is disclosed to include associating with each register a symbolic expression selected from a set of possible symbolic expressions, locating an operation, if any, that is next within the sequence of operations and setting that operation to be a working operation, where the working operation has associated therewith a destination register and zero or more source registers, and processing the working operation when the working operation and any symbolic expressions of its source registers, if any, match at least one of a set of rules, where each rule specifies that the working operation must match a subset of the operation set, where each rule also specifies that the symbolic expressions, if any, of any source registers of the working operation must match a subset of the possible symbolic expressions, and where the rule also specifies a result, then posting the result as the symbolic expression of the destination register.

摘要： A method and apparatus for optimizing a sequence of operations adapted for execution by a processor is disclosed to include associating a symbolic expression with each of at least a subset of the registers, holding a set of dependency indications that specify for each particular symbolic expression which, if any, of the other symbolic expressions must be emitted as operations prior to emitting the particular symbolic expression, locating an operation, if any, that is next within the sequence of operations and setting that operation to be a working operation and processing the working operation. Processing is performed by handling the working operation by a combination of updating zero or more of the symbolic expressions and emitting zero or more of the symbolic expressions as operations, identifying which, if any, of the symbolic expressions that were updated in process were updated such that they must be emitted prior to which other, if any, of the symbolic expressions, and then updating the dependency indicators to include any such dependencies, and identifying which, if any, of the symbolic expressions that were updated in process were updated such that they no longer need to be emitted prior to which other, if any, of the symbolic expressions, and then updating the dependency indicators to remove any such dependencies.
