C++ to C Compiler
Our Solution for C++
The emmtrix C++ to C Compiler (eCPP2C) automatically translates your C++ source code into analyzable C code. The design goal was to keep the binary compilation of the original C++ code and the binary compilation of the translated C code mostly identical. This guarantees the functional correctness of the generated C code. eCPP2C utilizes the LLVM/Clang compiler technology to enable support of the latest features of the fast evolving C++ standard. In combination with emmtrix Parallel Studio, eCPP2C enables software parallelization of C++ applications.
Our C++ Parallelization Workflow
The emmtrix C++ to C Compiler is our solution to support parallelization of C++ software within emmtrix Parallel Studio. In general, the C++ standard is evolving in a 3-year release cycle (starting from 757 pages in C++03 to over 1800 pages in C++20). As a result of this rapid evolution, only a selected number of software tools supporting C++ compliant compilation are available. The additional C++ translation step (in contrast to supporting C++ natively in ePS) allows to reuse the proven-in-use Clang frontend of the LLVM project. This provides a future-proof support of the C++ language with only a limited effort required when adapting to new language versions.
- Translation of C++ to C source code
- Utilizes latest LLVM/Clang compiler technology
- Gurantees functional correctness of generated C code by verification tool
- eC++2C qualification kit (ISO 26262, DO-178C/330 or any comparable standard) can be provided on request
- Demystifies how your C++ code is compiled to assembler
- Can be used in combination with (certified) C compilers and C code analysis tools
- Is integrated into emmtrix Parallel Studio GUI to enable C++ code parallelization
Supported C++ Language Features
There are only two problematic C++ features that are hard to support and will only be supported on request:
- Exceptions have no equivalent language construct in C
- Virtual classes would result in function pointers within the generated C code and that would brake the parallelization workflow.
Beyond that the emmtrix C++ to C Compiler is under active development and it is planned to support the full feature set of the C++17 (ISO/IEC 14882:2017) standard.
