Abstract
Official abstract text for this publication.
Techniques provided herein facilitate just-in-time compilation of source code, such as a script, during execution. According to some embodiments, a tracelet is limited to a single basic block of code. The data types of variable values provided by one or more variables used in the single basic block of code are known by generalized categories, rather than only being known by specific data types. Accordingly, guard code associated with each tracelet, which ensures that variable values received by the tracelet though the variables are of the data types expected by the tracelet's associated code body, can use generalized data types. The tracelet can contain code body that can handle input values that meet those generalized data types. A generalized data type can be defined according to one or more common characteristics shared by two or more specific data types.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method comprising: receiving, by a computer system, a request for executing a script; identifying, by the computer system, a basic block of code in the script to be executed, the basic block including one or more variables that provide input values to the basic block; determining a set of specific data types corresponding to current variable values provided by the variables during current execution of the basic block of code; det…
