and certain binary files. Unlike most other research compilers, ROSE is aimed to enable non-experts to leverage compiler technologies to build their own custom software analyzers and optimizers.

The infrastructure

ROSE consists of multiple front-ends, a midend operating on its internal intermediate representation (IR), and backends regenerating (unparse) source code from IR. Optionally, vendor compilers can be used to compile the unparsed source code into final executables.

ROSE uses the Edison Design Group's C++ front-end to parse C and C++ applications. Fortran support, including F2003 and earlier F77/90/95 versions, is based on the Open Fortran Parser (OFP) developed at Los Alamos National Laboratory

The ROSE IR consists of an abstract syntax tree

Abstract syntax tree

In computer science, an abstract syntax tree , or just syntax tree, is a tree representation of the abstract syntactic structure of source code written in a programming language. Each node of the tree denotes a construct occurring in the source code. The syntax is 'abstract' in the sense that it...

, symbol tables, control flow graph, etc. It is an object-oriented IR with several levels of interfaces for quickly building source-to-source translators. All information from the input source code is carefully preserved in the ROSE IR, including C preprocessor control structure, source comments, source position information, and C++ template information (e.g., template arguments).

ROSE is released under a BSD-style license. It targets Linux
