714 38

Abstract:

A method for dispatching a remote debugging agent (RDA), involving embedding the RDA in a target program to obtain a remotely debuggable target program, submitting the remotely debuggable target program to a distributed computing environment, wherein the distributed computing environment includes a plurality of nodes, executing the remotely debuggable target program on at least one of the plurality of nodes, establishing a connection between the RDA and a central debugging tool, and debugging the remotely debuggable target program using the central debugging tool.

Abstract:

A system and method provides for variable target outputs from a compiler with only a single execution. The compiler includes a front end, a generic back end, and plurality of individual back ends that are dynamically loaded by the compiler during execution. The front end produces an abstract syntax tree which is then processed by the generic back end and the individual back ends to produce a number of back end trees, each adapted for a specific back end, and representative of the desired structure of the various target outputs, including target code files, or events. The generic back end traverses the abstract syntax tree, and on each node of the tree, invokes each back end that has a node of its back end tree attached thereto. The back end can then modify its own back end tree, and attach further back end nodes to other nodes of the abstract syntax tree. In turn the generic back end will invoke such added attached nodes, until all attached back end nodes on all the nodes of the abstract syntax tree have been processed.
