摘要： A mechanism for tracking the control flow of instructions in an application and performing one or more optimizations of a processing device, based on the control flow of the instructions in the application, is disclosed. Control flow data is generated to indicate the control flow of blocks of instructions in the application. The control flow data may include annotations that indicate whether optimizations may be performed for different blocks of instructions. The control flow data may also be used to track the execution of the instructions to determine whether an instruction in a block of instructions is assigned to a thread, a process, and/or an execution core of a processor, and to determine whether errors have occurred during the execution of the instructions.

摘要： Techniques for selectively translating resource requests from a program running on a computer system are disclosed. The resource request may be a request to access a file, library file, API, etc. The resource request may be a system call or library call. The computer program may be non-native to the computer system. Translation of resource requests may occur within the operating system or outside it. A resource request containing a reference to a first path and file name may be selectively translated by altering the resource request to contain a reference to a second path and file name. After selectively translating a request, he request is caused to be serviced. A resource request may be serviced by forwarding it to an operating system, and a result may be sent back to the program.

摘要： A method for executing non-native binaries on a host computer architecture comprises receiving the guest executable binary into a computer readable medium. The guest executable binary is executed on the host computer architecture by translating the guest executable binary into a translated executable binary. Each instruction of the translated executed binary is then executed on the host computer architecture. Signals are responded to by placing signal information on a signal queue and deferring signal handling until a safe point is reached. A computer system implementing the method is also provided.
