Abstract: A method for executing a machine code based on a dynamic language is disclosed. An execution guard is created as a value stored in a data structure. The value is representative of an expected condition or a set of conditions for a reusable portion of the machine code. The value representative of the expected condition(s) is compared to an actual value encountered later during execution of a portion of the machine code. The reusable machine code is executed if the actual value corresponds with the value representative of the expected condition(s). The execution guard is invalidated if any of the expected conditions changes.

Abstract: Methods, systems, and computer program products are provided for profiling source code to enable improved source code execution. A runtime engine includes a parser, a bytecode generator, an execution controller, an interpreter, a just-in-time (JIT) compiler, and a profile generator. The parser receives source code coded in a dynamic language and parses the source code to generate parsed source code. The bytecode generator converts the parsed source code to bytecode. The interpreter is configured to interpret the bytecode when enabled by the execution controller. The JIT compiler is configured to compile the bytecode when enabled by the execution controller. The profile generator generates profile information from the bytecode and stores the profile information. The execution controller enables the interpreter or the JIT compiler to perform their respective functions based on the profile information.
