IBM® Open XL C/C++ for AIX® is IBM’s next-generation C/C++ compiler that facilitates the creation and maintenance of applications written in C/C++ for IBM Power. Taking advantage of the latest Power10 architecture, IBM Open XL C/C++ for AIX can generate code that leverages the capabilities of Power10 to maximize your hardware utilization.

IBM Open XL C/C++ for AIX fully incorporates the Clang and LLVM compiler infrastructure so you can enjoy the combination of open-source technology and IBM's strength in compiler optimization technology. LLVM is an open-source compilation framework that is actively maintained by a large development community, supporting multiple architectures and programming languages. Clang is part of the LLVM compiler infrastructure that provides a language front-end and tooling infrastructure for the LLVM project.

The infrastructure of IBM Open XL C/C++ for AIX allows you to benefit from modern C/C++ language, common LLVM optimizations, and GCC Compiler compatibility.
