摘要： A method, apparatus, and computer instructions in a data processing system for processing instructions and monitoring accesses to memory location ranges. An instruction for execution is identified. A determination is made as to whether the instruction is within a contiguous range of instructions. Execution information relating to the instruction is identified if the instruction is within the contiguous range of instructions. With memory location accesses, an access to a memory location is identified. A determination of whether the memory location is within a contiguous range of memory locations is made. Access information is identified if the memory location is within the contiguous range of memory locations.

摘要： A method, apparatus, and computer instructions in a processor for associating a data type with a memory location. The type is associated with a location by means of metadata that is generated and manipulated by hardware instructions that are typically generated by a compiler as it generates the other instructions that comprise the machine code version of a program. A determination is made as to whether a data value about to be stored is of the required data type for that location. The hardware indicates an error condition if the types do not match.

摘要： A method, apparatus and computer instructions for hardware assist for autonomically patching code. The present invention provides hardware microcode to a new type of metadata to selectively identify instructions to be patched for specific performance optimization functions. The present invention also provides a new flag in the machine status register (MSR) to enable or disable a performance monitoring application or process to perform code-patching functions. If the code patching function is enabled, the application or process may patch code at run time by associating the metadata with the selected instructions. The metadata includes pointers pointing to the patch code block code. The program code may be patched autonomically without modifying original code.

摘要： A method, apparatus, and computer instructions for autonomically counting selected branch instructions executed in a processor to improve branch predictions. Counters are provided to count branch instructions that are executed in a processor to collect branch statistics. A set of branch statistics fields is allocated to associate with a branch instruction. When a program is executed, the stored statistics allows the program to look at the branch statistics in the counter to perform branch prediction. Hence, a user may use branch statistics values from the hardware counter to perform analysis on application code.

摘要： A method, apparatus, and computer instructions for processing instructions. Responsive to receiving an instruction for execution in an instruction cache in a processor in the data processing system, a determination is made as to whether an indicator is associated with the instruction and whether the instruction is of a certain type within a range of instructions. An interrupt is generated if the indicator is associated with the instruction and the instruction is of the certain type within the range of instructions.

摘要： A method and system for determining the memory utilization of a heap are provided. With the method and system, object allocations and optionally, possible memory freeing events are used to initiate a mark-and-count operation. The mark-and-count operation marks the live objects and maintains a running count of their memory bytes allocated to the live objects, referred to as a live count. The execution of the mark-and-count operation may be dependent upon various criteria including thresholds, functions of the live count, peak live counts, number of memory bytes allocated since a previous mark-and-count operation was performed, and the like. In addition to the live count, a peak live count may be obtained and updated as new peak live counts are identified. When the peak live count is updated, additional information may be obtained via a heap dump, arcflow tree, or the like.

摘要： The present invention is directed to a system, method and instructions for handling path flow exception and finalization processing in an object oriented programming language. Initially, each instrumentation method is checked for a code to indicated an exception being thrown. A hook is inserted before the exception code and identifies the method throwing the exception. Methods must also be checked for exception tables. When an exception table is found, then a hook is inserted at the entry point of each exception handler for every entry in the exception table. This hook identifies the method which catches the exception.

摘要： A method and system for enabling the monitoring of software executing on a computer system. The system inserts monitor instrumentation without recompiling the source code of the program. Encapsulation of the target routine does not disrupt the relative addressing of the target routine since an instruction is simply replaced. No instructions are added to the target routine. User specified entry and exit routines are used to collect selected performance and system state data. Instrumentation code is provided to link the target routines to the user specified entry and exit routines. The standard link interface allows the entry and exit routines to be written in high level languages.

摘要： The present invention is directed to a system and method for monitoring system performance by using a multi-phase approach. The first phase, referred to as the burst counting phase, utilizes a set of counters to identify calls and returns which are heavily used. In the second phase, referred to as the instrumentation phase, the performance characteristics of the "hot spots" are monitored through the use of hardware counters. In a symmetrical multi-processor embodiment, the performance profiler is active on all processors at the same time. Frequently executed code paths are identified in a manner that is minimally-intrusive to the system as a whole, and uses relatively little storage. The user may specify a threshold count, after which hardware monitoring begins, and the user may specify the type of hardware performance data collected. After both phases of the performance monitor are run, the data can be presented to the user in a variety of ways.
