Abstract: Removing invalid literal load values, and related circuits, methods, and computer-readable media are disclosed. In one aspect, an instruction processing circuit provides a literal load table containing one or more entries comprising an address and a cached literal load value. Upon detecting a literal load instruction in an instruction stream, the instruction processing circuit determines whether the literal load table contains an entry having an address of the literal load instruction. If so, the instruction processing circuit removes the literal load instruction from the instruction stream, and provides the cached literal load value stored in the entry to at least one dependent instruction. The instruction processing circuit further determines whether an invalidity indicator for the literal load table has been received. If so, the instruction processing circuit flushes the literal load table. The invalidity indicator may be generated responsive to modification of a constant table.

Abstract: Systems, methods, and devices for executing a function in a dynamically-typed language are described herein. In one aspect, a method includes generating a function selection decision tree based on one or more specializations of a generic function and one or more function inputs via an electronic device. The method further includes selecting one of the specializations or the generic function based on an input type of at least one function input via the electronic device. The method further includes calling the selected specialization or generic function via the electronic device. Another aspect of the subject matter described in the disclosure provides a method of executing a function in a prototype-based dynamically-typed language. The method includes maintaining a list of calls to one or more specializations of the function via the electronic device. The method further includes creating or destroying a specialization of the function via the electronic device. The method further includes updating calls to the created or destroyed specialization via the electronic device. Advantageously in certain embodiments, selection logic overhead can be reduced using criteria that can utilize different weightages for one or more inputs based on heuristics or runtime information.
