ARM has updated it’s C/C++ compiler toolchains.
C and C++ update for Arm Compiler 6:
As you are hopefully aware, Arm Compiler 6 has been available for 3+ years now, and has grown in maturity, and optimization quality release on release. As I write this, the latest available version is 6.8, and 6.6 has been qualified for use in safety-related development. We offer full support for the latest Arm processors, across the Cortex-A, R, and M, and SecureCore families. Arm Compiler 6 is available within DS-5 and Keil MDK toolchains. Furthermore the qualified version is available for purchase stand-alone. Arm Compiler 6 is based on the LLVM framework, using the modern Clang compiler front-end, and this is reflected in the name of the executable, Armclang. The compiler is then integrated into the full Arm tools suite, enabling use of legacy assembler code built with Armasm, as well as gas format assembler directly with Armclang. Finally the Arm linker (Armlink) brings in the optimized C and C++ libraries, or if desired the size optimized Arm C MicroLib library, as well as (optionally) implementing link-time optimizations across the source code.[…]
