摘要： A method and system for reverting a process in an in-line instrumented state to an uninstrumented state. In one embodiment, the present invention modifies selected text segment portions from the process to be uninstrumented. The present embodiment then unmaps instrumented code space such that the instrumented code space is inaccessible to the process. In this embodiment, provided an instruction pointer resides in the instrumented code space, the present invention updates the instruction pointer to uninstrumented code space. The present embodiment also executes the process and, provided the process generates a fault by seeking to access an address in instrumented code space, provides a corresponding address in uninstrumented code space. In one embodiment, the present invention then continues execution at the address in instrumented code space.

摘要： A method and system for reverting a process in an in-line instrumented state to an uninstrumented state. In one embodiment, the present invention modifies selected text segment portions from the process to be uninstrumented. The present embodiment then unmaps instrumented code space such that the instrumented code space is inaccessible to the process. In this embodiment, the present invention also cleans a call stack of the process by unwinding the call stack and resetting the storage locations for return pointers from the instrumented code space to uninstrumented code space.

摘要： Method and apparatus for dynamic instrumentation of an executable application program. The application program includes a plurality of functions, each function having an entry point and an endpoint. When the application is executed, a shared memory segment is created for an instrumentation program and the application program. Upon initial invocation of the original functions in the application program, corresponding substitute functions are created in the shared memory segment, the substitute versions including instrumentation code. Thereafter, the substitute functions are executed in lieu of the original functions in the application program.

摘要： Techniques for cloning programming code are disclosed. In an embodiment, the cloned code is in the form of functions in the C language. Further, in a method embodiment, a clone of a function is invoked, and information mapping the clone to the function is generated. At link time, if no function body of the clone is accessible by a linker, then the linker uses information mapping the clone to the function to satisfy a linker's requirement. At load time, if no function body of the clone is accessible by a loader, then the loader, based on the mapping information, allows selection of a body of the function. However, if the body function of the clone is accessible by the loader, then the loader allows selection of the body of the clone.

摘要： Method and apparatus for handling calls from relocated instrumented functions to functions that expect a return pointer value in an original address space. In various embodiments of the invention, instrumented versions of selected functions of an executable program are generated and stored in a relocation address space. When a function is called by a function in the relocation address space, a return pointer register stores a first return-pointer value that is an address in the relocation address space. The address in the original address space that corresponds (logically) to the first return-pointer value is identified as an original return-pointer value. The first return-pointer value is associated with the original return-pointer value, references to the original return-pointer value are substituted for references to the first return-pointer value, and the instruction at the address indicated by the original return-pointer value is replaced with a breakpoint. When the breakpoint is encountered upon return of control at the original return-pointer value, the first return-pointer value that is associated with the original return-pointer value is obtained, and control is transferred to the instruction at the address referenced by the first return-pointer value.

摘要： A computer-implemented method for performing structure layout optimization of a data structure in a multi-threaded environment is provided. The method includes determining a set of code concurrency values. The method also includes calculating a set of cycle gain values. The method further includes employing the set of cycle gain values and the set of code concurrency values to create a field layout graph, which is configured to illustrate relationship between a set of data fields of the data structure. The method yet also includes employing a cluster algorithm to the field layout graph to create a set of clusters. Each cluster of the set of clusters is employed to generate a cache line.
