The ROSE compiler framework, developed at Lawrence Livermore National Laboratory (LLNL), is an open-source software compiler infrastructure to generate source-to-source analyzers and translators for multiple source languages including C (C89, C99, Unified Parallel C (UPC)), C++ (C++98, C++11), Fortran (77, 95, 2003), OpenMP, Java, Python, and PHP.
It also supports certain binary files, and auto-parallelizing compilers by generating source code annotated with OpenMP directives. Unlike most other research compilers, ROSE is aimed at enabling non-experts to leverage compiler technologies to build their own custom software analyzers and optimizers.
