What IBM XL C/C++ for AIX can do for your business

IBM® XL C/C++ for AIX® is a compiler that facilitates the creation and maintenance of applications that are written in C/C++ for IBM Power® Systems. It generates code that leverages the capabilities of POWER8® and the latest POWER9™ architectures and maximizes your hardware utilization. V16.1 provides new C and C++ compilers adopting the open-source Clang technology. The new compilers provide enhanced C and C++ language standards support including C11, C++11, and C++14 as well as GCC compatibility. The existing C and C++ compilers continue to be available for use.


Maximize your Power hardware ROI

Capitalizes on the POWER8 and POWER9 architectures; offers automatic parallelization of sequential programs to exploit modern multi-core processors.

Optimize application performance

Provides industry leading advanced optimization technologies including the high-performance libraries, profile-directed feedback (PDF) support, and interprocedural analysis (IPA).

Migrate applications to Power easily

In addition to C89, C99, C++98, and C++03 full support, the Clang-based front end fully supports C11, C++11, and C++14 while the XL-based front end supports a subset of the C11 and C++11 standards.

Improve developer productivity
