摘要： An aspect includes enabling and disabling execution of a run-time instrumentation facility. An instruction for execution by the processor in a lesser privileged state is fetched by the processor. The instruction is executed based on determining, by the processor, that the run-time instrumentation facility permits execution of the instruction in the lesser-privileged state and that controls associated with the run-time instrumentation facility are valid. The run-time instrumentation facility is disabled based on the instruction being a run-time instrumentation facility off (RIOFF) instruction. The disabling includes updating a bit in a program status word (PSW) of the processor to indicate that run-time instrumentation data should not be captured by the processor. The run-time instrumentation facility is enabled based on the instruction being a run-time instrumentation facility on (RION) instruction. The enabling includes updating the bit in the PSW to indicate that run-time instrumentation data should be captured by the processor.

摘要： Aspects of the invention relate to executing a run-time-instrumentation EMIT (RIEMIT) instruction. A processor is configured to capture the run-time-instrumentation information of a stream of instructions. The RIEMIT instruction is fetched and executed. It is determined if the current run-time-instrumentation controls are configured to permit capturing and storing of run-time-instrumentation information in a run-time-instrumentation program buffer. If the controls are configured to store run-time-instrumentation instructions, then a RIEMIT instruction specified value is stored as an emit record of a reporting group in the run-time-instrumentation program buffer.

摘要： Embodiments of the invention relate to performing run-time instrumentation. Run-time instrumentation is captured, by a processor, based on an instruction stream of instructions of an application program executing on the processor. The capturing includes storing the run-time instrumentation data in a collection buffer of the processor. A run-time instrumentation sample point trigger is detected by the processor. Contents of the collection buffer are copied into a program buffer as a reporting group based on detecting the run-time instrumentation sample point trigger. The program buffer is located in main storage in an address space that is accessible by the application program.

摘要： A mechanism is provided for operating a computing system, in which an inner virtual machine translates first instructions, which are supported by the inner virtual machine, into second instructions, which are supported by an outer virtual machine. The mechanism encodes, in the inner virtual machine, third instructions into the second instructions into which the first instructions are translated, the third instructions including hints for facilitating an execution of the second instructions, and, in an event the hints are supported by the outer virtual machine, initiating the execution of the second instructions while utilizing the hints by the outer virtual machine to achieve an increased efficiency of the execution of the second instructions.

摘要： Optimizing a program having a plurality of functions. The program is optimized using an optimization technique that requires breaking a calling convention. The first function of the plurality of functions is modified as a result of optimizing. A name of the first function is mangled to form a unique first mangled name. Mangling comprises changing the name. The unique first mangled name includes, as a result of mangling, first information conveying at least in part how the first function was modified. A second function of the plurality of functions, being a caller of the first function, is also modified to correctly invoke first function using the unique first mangled name to apply the optimization technique. A compilation tool can, after optimizing, use the first information to take a first action with respect to the first procedure, wherein the compilation tool otherwise would require the calling convention to remain unbroken in order to take the first action.

摘要： In the field of mixed 16-bit and 32-bit code, a method and mechanism are provided to implement alterations in the dynamic portion of memory containing the data objects used by code in the 16-bit environment so that such data is accessible to code from the 32-bit environment. The code necessary to implement the method is generated automatically by an enhanced compiler on identifying 16-bit linkage in the 32-bit code. Once the data objects in the stack are accesible to the 32-bit code, a function in the 16-bit code can successfully call a function in 32-bit code.
摘要翻译：在混合16位和32位代码领域，提供了一种方法和机制来实现包含16位环境中的代码所使用的数据对象的存储器的动态部分的变更，以便这些数据可被代码访问从32位环境。实现该方法所需的代码由增强型编译器自动生成，用于识别32位代码中的16位连接。一旦堆栈中的数据对象可以访问32位代码，16位代码中的一个功能就可以成功地调用32位代码中的函数。
