摘要： A computer system employing memory virtualization may employ a function-based technique for virtual-to-physical address translation. A function-based translation technique may involve replacing a generic trap handler and one or more translation table look-ups with a function to compute a corresponding physical address from a given virtual address. The computer system may be configured to determine a translation function dependent on mappings in one or more translation tables. The computer system may be configured to reorganize a memory, to reorganize one or more translation tables, or to allocate different blocks of memory to an application prior to determining a translation function. Different applications or threads executing on the computer system may employ different translation functions. Different regions of memory may be accessed using different translation functions. Some virtual addresses may be translated using a function while others may be translated using one or more translation table look-ups.

摘要： A range check elimination loop structure is provided. The range check elimination loop structure includes a pre-loop structure based on an original loop structure, where the pre-loop structure is capable of testing indexing expressions for underflow. In addition, a main loop structure having indexing expressions based on the original loop structure is included. The indexing expressions included in the main loop preferably cannot produce an underflow or an overflow. Also included in the range check elimination loop structure is a post-loop structure based on the original loop structure that is capable of testing indexing expressions for overflow.

摘要： Methods and apparatus for enabling a register allocator to build a calling convention are disclosed. According to one aspect of the present invention, a computer-implemented method for generating code associated with a calling convention includes obtaining compilable source code, and identifying at least one argument associated with the calling convention. The location of the argument with respect to memory space is described by a register mask. The method also includes performing a register allocation using a register allocator that is arranged to allocate registers. During the register allocation, code associated with the calling convention is produced automatically by the spill-code mechanism in the allocator without requiring the use of a specialized prolog or epilog code generator.

摘要： Systems and methods for automatically providing an adapter or a stub in a runtime environment are provided. An adapter generator is provided with input parameters that are in turn processed and input to a compiler. The compiler, in turn, is coupled to an adapter library used to store the generated adapters. The adapter library, in turn, provides adapters, on demand to a runtime system when executing a bytecode, or a series of bytecodes.

摘要： Methods and apparatus for handling exceptions as a part of normal program control flow are disclosed. According to one aspect of the present invention, a method for processing an exception in an object-based system includes obtaining source code that includes a code segment which is arranged to explicitly specify instructions pertaining to an exception check. The method also includes creating a final internal representation of the source code at least in part by removing a call associated with the exception check, and generating machine code associated with the final internal representation. In one embodiment, the method further includes executing the machine code. In another embodiment, creating the final internal representation of the source code includes processing the exception check as a part of a control flow associated with the source code.

摘要： The aspects enable a computing device to allocate memory space to variables during runtime compilation of a software application. A first variable associated with a code segment within code being compiled may be identified and assigned a priority tag. A second variable associated with another code segment within the code being compiled may also be assigned a priority tag. A determination may be made regarding whether the first and second variables are contemporaneously live during execution, and whether legal storage location sets for the first and second variables overlap. The assigned priority tags may be used for assigning storage locations to the first and second variables based on the determination.

摘要： The aspects enable a processor to concurrently execute a first serial language code (e.g., HTML) embedding a second serial language code (e.g., JavaScript®) during a page load operation by a browser. A parser parses the first serial language code until a segment of the embedded second serial language code is encountered. The segment of embedded second serial language code is extracted for execution by an execution engine, which proceeds concurrently with speculative parsing of the first serial language code. Code generated by execution of second serial language code is evaluated to determine if it is well formed, and a partial rollback and re-parsing of the first serial language code is performed if the code is not well formed.
