摘要： Programs are rarely self-contained in software environments. They depend on other programs or shared subsystems like language run time and operating system libraries for various functionalities. A change in one of the external subsystems may affect the program and one or more other external subsystems.A method or system collects and propagates information about dependency between logical abstractions within a binary file (e.g., basic block, procedure, etc.), dependency between binary files, and dependency between subsystems (e.g., programs, component libraries, system services, etc,) In one example, such dependency information is exposed to a tool (e.g., test tool, software development tool, etc.) via an application programming interface. A tool mines this information to manage testing, determine risks of change, or manage software development. The tool may also be integrated into the method or system.

摘要： Each component binary in a heterogeneous program is translated from a platform-specific instruction set into a set of intermediate representation (IR) instructions that are platform-neutral. The IR instructions are grouped into IR code blocks, the IR code blocks into IR procedures, and the IR procedures into IR components to create an intermediate representation hierarchy for the program. An application program interface is provided that permits user access to the IR hierarchy for instrumentation, optimization, navigation, and manipulation of the IR hierarchy. The transformed IR hierarchy is then translated into platform-specific instructions and output as a modified binary. The user can designate a different platform for the output translation of a code block than the platform for which the code block was originally written. Prologue and epilog code is added to contiguous blocks that are translated into different architectures. The modified binary can be iterated through the translation and transformation process to produce multiple versions of the heterogeneous program.

摘要： A computer system is directed to convert a program written as a plurality of high level source code modules into corresponding machine executable code. The source code modules are compiled into an object code module, and the object code modules are translated into a single linked code module in the form of a register translation language and logical symbol table compatible with a plurality of computer system hardware architectures. The source code program structures are recovered from the linked code module, and the linked code module is partitioned into a plurality of procedure, and instructions of each of the procedures grouped into basic blocks. A procedure flow graph is constructed for each of the procedures, and a program call graph is constructed for the linked code module. The linked code module is modified by eliminating dead code and moving loop-invariant code from loops. The modified linked code is converted into machine executable code compatible with a target one of said plurality of computer system hardware architectures.

摘要： An application program interface (API) into an hierarchical intermediate representation (IR) of a heterogeneous program enables the navigation and modification of the IR at all levels of the hierarchy. Additional functions provide information about the IR that can be employed by a user in understanding the logic flow of the program and by an output translator to convert the IR into blocks of platform-specific instructions for a new version of the heterogeneous program. The API functions are also utilized by pre-defined program tools to instrument and optimize the IR, and thus the heterogeneous program created from the IR.

摘要： Pre-defined performance tools enable instrumentation and optimization of a heterogeneous program by modifying a platform-neutral intermediate representation (IR) of the program. The intermediate representation is hierarchy of base elements that correspond to instructions, code blocks, procedures and components within the program. Each base element exports an application program interface that provides for navigation, querying and modification of the corresponding element in the hierarchy. An application program interface for the entire intermediate representation includes the application program interfaces for the individual elements along with additional functionality. A user can request instrumentation and optimization of any level of the intermediate representation hierarchy and the performance tools perform the required modifications to the intermediate representation. When a modification requires inserting instructions, the performance tools add prologue and epilog code to connect the inserted instructions with the original intermediate representation instructions. When the intermediate representation instructions are translated into platform-specific instructions and executed, the modifications made to the intermediate representation provide the instrumentation and/or optimization of the heterogeneous program.

摘要： An output translator provides for cross module representations of components within a heterogeneous program by translating modifying a platform-neutral intermediate representation (IR) of the program into platform-specific instructions for different architectures. The intermediate representation is hierarchy of base elements that correspond to instructions, code blocks, procedures and components within the program. Blocks of instructions that were originally written for one architecture can be translated from the intermediate representation into platform-specific instructions for a different architecture. The output translator provides any necessary code to interface contiguous code blocks that are emitted in different instruction sets.
