LENS defines an external representation +of a program in XML to store useful information +that is accessible based on program structure, including loop +structure information.</p> + +<p>Lens defines a flexible naming scheme for program components +based on XPath and the LENS XML document structure. This allows +users and tools to selectively query program behavior from a +uniform interface, allowing users or tools to ask a variety of +questions about program components, which can be answered by any +tool that understands the query. Queries, metrics and program +structure are all stored in the LENS file, and are annotated with +version names that support historical comparison and scientific +record-keeping.</p> + +<p>Compiler writers can use LENS to expose results of transformations +and analyses for a program easily, without worrying about display or +handling information overload. This functionality has been +demonstrated using LLVM. LENS uses LLVM for two purposes: first, to +generate the initial program structure file in XML using an LLVM +pass, and second, as a demonstration of the advantages of selective +querying for compiler information, with an interface built into LLVM +that allows LLVM passes to easily respond to queries in a LENS file.</p> + +</div> + <!--=========================================================================--> <div class="www_subsection"> <a name="trident">Trident Compiler</a><br> _______________________________________________ llvm-commits mailing list llvm-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits
