Software upgrade builds on open source LLVM technology

The flexible and modern Clang and LLVM infrastructure provides a solid foundation for ARM’s code generation tools. Clang is a C/C++ compiler front end based on a modular architecture with well-defined interfaces for applying complimentary tools such as code analyzers and code generators. Clang also offers improved diagnostic capabilities, leading to higher quality code and shorter development cycles.

LLVM is an extensible compiler framework which is well suited for advanced code generation techniques such as link-time code generation and just-in-time compilation. LLVM’s modular framework makes it easier to develop and test new optimizations, leading to better performing code and lower power consumption.

“ARM has invested heavily in the development and adoption of open source technologies such as Eclipse, GNU, and Clang and LLVM,” said Hobson Bullman, general manager of development solutions, ARM. “The ARM Compiler 6 extends this investment even further, bringing together the velocity of open source development with the stability and services that come with commercial products, creating a best-case scenario for ARM’s customers.”

“Clang and LLVM have become essential technologies for high-volume mobile platforms,” said Travis Lanier, director of product management, Qualcomm Technologies, Inc. “Qualcomm Technologies applauds this decision by ARM to improve Clang and LLVM technology for the benefit of the mobile ecosystem. We look forward to the continued close collaboration with ARM in this area.”

ARM is at the forefront of improving LLVM technology for the ARM architecture, contributing architecture support, testing infrastructure, and performance improvements to the open source. ARM Compiler 6 brings LLVM technology to ARM developers as a set of professional development tools with additional benefits:

• Tighter integration: ARM Compiler 6 is a full code generation toolchain consisting of compiler, linker, assembler and libraries. Its integration in the ARM DS-5 Development Studio provides a full C/C++ software development environment
• Optimized for ARM: Highly optimized libraries provide superior performance and code size for embedded applications, maximizing software performance and reducing costs
• Professionally supported and maintained - ARM Compiler 6 and DS-5 are actively supported, validated, documented and maintained by ARM’s globally distributed technical experts, ensuring rapid issue resolution and faster time to market
• Commercially licensed - ARM Compiler 6 is GPL-free and distributed under a commercial license, giving users flexibility with regard to ownership of derivative works

ARM Compiler 6 supports ARM Cortex-A50 processor series and is available as part of the DS-5 Development Studio Ultimate Edition, available April 2014.
