Overview

Build, Modernize, and Optimize C/C++ Applications

IBM Open XL C/C++ for AIX is the next-generation C/C++ compiler that facilitates the creation and maintenance of applications written in C/C++ for use on IBM Power platforms to maximize your hardware utilization.

Features

Key features

Fully incorporates the LLVM1 and Clang2 compiler infrastructure for C/C++. Enjoy modern C/C+ language and common LLVM optimization features such as LLVM diagnostic and reporting capabilities.

Provides language extensions to support vector multimedia extension (VMX) and vector scalar extension (VSX) programming.

Enable licensing of IBM Open XL compilers on virtual servers for the required capacities when transitioning to hybrid cloud. Monthly licensing per the virtual process core charge unit is available.

Fully exploits Power10 architecture. Provides Power10 architecture options, built-in functions, and tuned library functions to maximize the hardware ROI.

Use cases

Use cases

Link Time Optimization (LTO)

Enables you to take advantage of intermodular optimizations without making any significant changes to the makefiles or build system. ThinLTO is also introduced, which delivers big improvements in both compile time and memory usage.

 Explore Link Time Optimization
Enable continuous delivery

Take advantage of both common LLVM optimizations and IBM’s industry-leading technologies to improve workload performance.
High-performance libraries

Provides a set of libraries for high-performance mathematical computing including the Mathematical Acceleration Subsystem (MASS) and Basic Linear Algebra Subprograms (BLAS) libraries.
