Abstract: Extended types are defined for functions that are called by function handles in a programming environment. The extended types can be accessed and used by a computing system to improve compile-time and run-time performance of the computing system.

Abstract: Systems and methods for just-in-time compilation are disclosed. The systems and methods can be used to generate composite blocks, reducing program execution time. The systems and methods can include generating single-trace blocks during program execution. Upon satisfaction of a trigger criterion, single-trace blocks can be selected for compilation into a composite block. The trigger criterion can be a number of executions of a trigger block. Selecting the single-trace blocks can include identifying blocks reachable from the trigger block, selecting a subset of the reachable blocks, and selecting an entry point for the composite block. The composite block can be generated from the single-trace blocks and incorporated into the program control flow, such that the composite block is executed in place of the selected single-trace blocks.

Abstract: The exemplary embodiments may provide an approach to finding and identifying the correlation between the invoking code and the invoked code by correlating the timestamps of contextual information of code in the invoking code and invoked code. As a result, developers have information during investigating the programs and can use the information to identify a region of interest to narrow down a performance problem in the invoking code efficiently. As a result, development productivity can be improved.

Abstract: A device may identify a first compiled block with an original constraint and an additional constraint. The first compiled block may be identified based on a program counter value and may include compiled information relating to a first segment of program code, linking information associated with a second compiled block, and information distinguishing the original constraint from the additional constraint. The original constraint may relate to a type of variable used in the first segment of programming code. The additional constraint may relate to a variable used in a second segment of programming code associated with the second compiled block. The device may copy information of the first compiled block to generate a third compiled block that lacks the additional constraint. The device may execute the third compiled block to execute a program associated with the programming code.

Abstract: A device receives programming code, corresponding to a dynamic programming language, that is to be executed by a computing environment, and executes the programming code. When executing the programming code, the device maintains a program counter that identifies an execution location within the programming code, and select blocks of the programming code based on the program counter. The blocks correspond to segments of the programming code, and are associated with type-based constraints that relate to types of variables that are used by the block. When executing the programming code, the device also compiles the selected blocks, caches the compiled blocks along with the type-based constraints, generates linking information between certain ones of the compiled blocks based on the type-based constraints, and executes the compiled blocks in an order based on the program counter, the type-based constraints, and the linking information.
