A computer system which includes a plurality of threads and a garbage collector that traces memory objects and identifies memory objects according to a three-color abstraction. The computer system also includes two methods of deleting compiled code in a self-modifying multi-threaded computer system. The computer system also utilizes a method of handling links between fragments of code in a self-modifying multi-threaded computer system. The computer system also handles patches between two pieces of code.

Method and system for dynamic memory management

A method and system multi-threaded fragment patching. The method provides a link in a self-modifying multi-threaded computer system between a first and a second piece of compiled code where the first piece of compiled code includes a control transfer instruction to the second piece of compiled code. The link is formed by inserting a patch from the first piece of compiled code to the second piece of compiled code. The patch may be a direct reference or a reference to an outlier.

Multi-threaded fragment patching

A system and method of direct invocation of Methods using class loaders. The method includes compiling a call to and a Method of a first class (assuming that the Method is final), determining whether the second class includes an instance of the Method of the first class, determining whether the instance of the Method of the second class overrides the Method of the first class, and altering the compiled code of the Method of the first class if the instance of the Method of the second class overrides the Method of the first class.

Direct invocation of methods using class loader

A method and a system of cache management using spatial separation of outliers. The system includes a dynamic compiler arranged to create compiled fragments of code having dominant code blocks and outliers. Memory coupled to the dynamic compiler is managed by a compiler manager such that dominant code blocks are stored in one portion of the memory and the outliers are stored in another portion of the memory. Storing the dominant path code separate from the outliers increases efficiency of the system.
