Embodiments of the present invention provide a method, system, and computer program product for qualifying changes to an instruction set in source code. In an embodiment of the invention, a method for quantifying changes to an instruction set in source code can be provided. The method can include receiving text in a code editor as an edit to source code of a computer program querying a data store of code change costs with at least a portion of the edit. The method additionally can include retrieving in response to the query a code change cost associated with the edit. Finally, the method can include displaying in the code editor the retrieved code change cost.

Automated and heuristically managed solution to quantify CPU and path length cost of instructions added, changed or removed by a service team

A method and system are provided for aspect scoping in a modularity runtime. The method includes declaring a set of aspects of a bundle as public aspects in a first aspect configuration file, and filtering the aspect configuration files imported by a bundle to the files from bundles on which the importing bundle has a dependency. The method includes declaring a set of aspects of a bundle as private aspects in a second aspect configuration file. At weaving of aspects at a bundle, the weaving includes: any aspects defined as private aspects; any aspects defined as public aspects; any imported aspects; and any first configuration files from exporting bundles are declared.

Embodiments of the present invention provide a method, system and computer program product for USING range validation during assembly of an assembly language program. In an embodiment of the invention, a method for USING range validation during assembly of an assembly language program has been provided. The method can include parsing assembler language source code loaded for assembly in an assembler executing in memory of a computer. The method also can include identifying a USING statement in the source code establishing a base address as the content of a register. Finally, in response to additionally identifying a subsequent statement in the source code that modifies the content of the register, a warning of an invalid USING range can be generated.

Using range validation in assembly language programming

A method, system and article of manufacture for simulating latency between software applications. There is provided a middleware component, e.g., a delay driver, within a multi-tier software product, the middleware component driver enables simulation of both latency and bandwidth restrictions experienced by the components in the multi-tier software product. The middleware component determines whether I/O request packets should be delayed, selects the number and types of I/O requests packets to be delayed and the amount of time to delay processing of the packets. Through the use of such a middleware component, a user is able to simulate various conditions experienced by the multi-tier software product.
