Abstract: Systems and methods are discussed that allow profile information to be reused by various versions of a program. One illustrative aspect includes a method for comparing versions of a program in binary format. The method includes finding equivalent contents in portions of two versions of the program, finding equivalent structure in the portions of the two versions, and forming a match when a portion of one of the two versions is an equivalence of a portion of the other of the two versions.

Abstract: 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.

Abstract: 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.

Abstract: 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.
