Abstract: Test coverage is enhanced by measuring various types of coupling between coverage tasks. The coupling measurements may be implicit coupling measurements, explicit coupling measurements, coding coupling measurements, performance coupling measurements, resource coupling measurements or the like. Coupling scores are calculated for coverage tasks and based thereon ranking of the coverage tasks or groups of coverage tasks may be determined The ranking may be utilized in selecting for which uncovered coverage task a test should be designed. The ranking may be utilized in computing a coverage measurement of a test suite. The ranking may be utilized to rank tests, based on the coverage tasks each test covers. Ranking of tests may be utilized for various purposes such as performing test selection.

Abstract: A method, system, and computer program product for operating system (OS) aided code coverage are provided. The method includes reading context information associated with a software process in response to a context switching event in an OS, the OS initiating the reading of the context information and controlling scheduling of the software process. The method further includes determining coverage information for code implementing the software process as a function of the context information in response to the OS reading the context information, and storing the coverage information as coverage data.

Abstract: A novel and useful apparatus for and method of associating a dedicated coverage bit to each instruction in a software system. Coverage bits are set every time the software application runs, enabling a more comprehensive and on-going code coverage analysis. The code coverage bit mechanism enables code coverage analysis for all installations of a software application, not just software in development mode or at a specific installation. Code coverage bits are implemented in either the instruction set architecture (ISA) of the central processing unit, the executable file of a software application, a companion file to the executable file or a code coverage table residing in memory of the computer system.

Abstract: A method for code optimization includes disassembling object code that has been compiled and linked, and identifying a function in the disassembled code, the function including store and restore instructions with respect to a register. The disassembled code is analyzed to locate a call to the function followed by an instruction to kill the register. The code is modified so as to eliminate the store instruction from the function when the function is invoked by the located call.

Abstract: A post-link optimization method for renaming non-volatile registers with unused volatile registers, then removing the non-volatile register store/restore instructions from a function prolog/epilog. The volatile registers are saved before each function call and restored immediately afterwards. The optimization method is worthwhile if all of the call instructions are rarely invoked relative to the function prolog/epilog. The method requires that the hot function be disassembled, but does not require the full control flow graph.

Abstract translation: 一种用于使用未使用的易失性寄存器重命名非易失性寄存器的后链优化方法，然后从函数prolog / epilog中删除非易失性寄存器存储/恢复指令。 每个功能调用之前保存易失性寄存器，并立即恢复。 如果所有的调用指令相对于函数prolog / epilog很少被调用，那么优化方法是值得的。 该方法要求热功能被拆卸，但不需要完整的控制流程图。
