C++ to C Compiler
(eCPP2C)

Our Solution for C++

The emmtrix C++ to C Compiler (eCPP2C) is a transpiler (source-to-source compiler) that 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 as close as possible. 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.

Supported C++ Language Features

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

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.

However, there is one C++ feature that poses a challenge and will only be supported upon request: exceptions, which do not have an equivalent language construct in C. Despite this obstacle, we are committed to providing comprehensive support for the latest C++ standard.
