摘要： A method, data processing system, and computer program product for managing a branch trace environment. In response to a branch being taken for a first branch instruction that is conditional and direct in the branch instructions, a performance monitoring unit stores an effective address of the first branch instruction into a first entry in a set of entries in a memory. The performance monitoring unit counts each branch not taken in processing the branch instructions occurring after the first branch instruction to form a branch count. In response to a branch being taken during processing of subsequent branch instructions in the branch instructions after the first branch instruction, the performance monitoring unit determines whether to create a second entry in the set of entries in the memory using the branch count with a set of rules identifying when the second entry is to be made.

摘要： Computer implemented method, system and computer usable program code for profiling the execution of an application that is both space- and time-efficient and highly accurate. A computer implemented method for profiling the execution of an application includes sampling execution characteristics of the application at a plurality of sampling points to provide samples, and deriving a calling context of the samples. The application is continuously executed between sampling points while additional profiling data is gathered.

摘要： An information handling system includes a memory, a processor, and an instruction tracking unit. The processor executes program code and, while the program code executes, the instruction tracking unit decodes a multi-purpose no-op instruction within the program code. In turn, the instruction tracking unit sends an interrupt to the processor, which invokes a profiling module to collect and store profiling data in a profiling buffer.
