emmtrix C++ to C Compiler

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.

Features

Translation of C++ to C11 (ISO/IEC 9899:2011) source code
Utilizes latest LLVM/Clang compiler technology
Gurantees functional correctness of generated C code by verification tool
eCPP2C 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
Integrated into emmtrix Parallel Studio GUI to enable C++ code parallelization

Supported C++ Language Features

The following list displays some of the C++ language features supported by the C++ to C Compiler:

Classes
Multiple inheritance
New/Delete
Namespaces
extern “C”
Using
Friends
Lambda expressions

Static assert
C++ casts
Auto
References
Rvalue references
Move semantic

…

The emmtrix C++ to C Compiler is under active development and it aims to support the full feature set of the C++17 (ISO/IEC 14882:2017) standard as well as common GCC / Clang language extensions.

Interested in having C++ exceptions supported? Even though this C++ feature does not have an equivalent we can provide a solution to you upon request (see contact details at the buttom of the page).

Verification Tool and Test Strategy

The emmtrix C++ to C compiler has a unique verification and testing strategy that guarantees that the generated C code is semantically equivalent to C++.
