摘要： Embodiments of the invention relate to implementing run-time instrumentation directed sampling. An aspect of the invention includes fetching a run-time instrumentation next (RINEXT) instruction from an instruction stream. The instruction stream includes the RINEXT instruction followed by a next sequential instruction (NSI) in program order. The method further includes executing the RINEXT instruction by a processor. The executing includes determining whether a current run-time instrumentation state enables setting a sample point for reporting run-time instrumentation information during program execution. Based on the current run-time instrumentation state enabling setting the sample point, the NSI is a sample instruction for causing a run-time instrumentation event. Based on executing the NSI sample instruction, the run-time instrumentation event causes recording of run-time instrumentation information into a run-time instrumentation program buffer as a reporting group.

摘要： A computer implemented method for determining when to change a representation type of at least one number stored in a memory of a data processing system. An operation is received in a processor of the data processing system. The operation references a number stored as a class of an object-oriented programming language. The number is stored as a first representation type. Responsive to the operation being biased towards the first representation type, a first counter is incremented. Responsive to the operation being biased towards a second representation type, a second counter is incremented. A counter reference is equal to a first value of the first counter subtracted from a second value of the second counter. Responsive to the counter reference exceeding a threshold number, representation of a subsequent number is changed from the first representation type to the second representation type.

摘要： A TRANSACTION ABORT instruction is used to abort a transaction that is executing in a computing environment. The TRANSACTION ABORT instruction includes at least one field used to specify a user-defined abort code that indicates the specific reason for aborting the transaction. Based on executing the TRANSACTION ABORT instruction, a condition code is provided that indicates whether re-execution of the transaction is recommended.

摘要： A computer implemented method, system, and computer usable program code for selective instruction scheduling. A determination is made whether a region of code exceeds a modification threshold after performing register allocation on the region of code. The region of code is marked as a modified region of code in response to the determination that the region of code exceeds the modification threshold. A determination is made whether the region of code exceeds an execution threshold in response to the determination that the region of code is marked as a modified region of code. Post-register allocation instruction scheduling is performed on the region of code in response to the determination that the region of code is marked as a modified region of code and the determination that the region of code exceeds the execution threshold.
