Overview

Arm Compiler provides the earliest, most complete, and most accurate support for the latest architectural features and extensions of the Arm architecture. Arm Compiler supports all the latest Arm Cortex, Neoverse, and SecurCore processors, including cores that are in development.

Arm Compiler is a mature toolchain that is tailored to the development of bare-metal software, firmware, and Real-Time Operating System (RTOS) applications. Arm Compiler is used by leading companies in a wide variety of industries, including automotive (ISO 26262), consumer electronics, industrial (IEC 61508), medical (IEC 62304), networking, railway (EN 50128), storage, and telecommunications. For HPC and scientific applications, see the Linux user-space C/C++ Compiler and Linux user-space Fortran compiler.

The Arm Compiler includes many powerful space-saving and performance-enhancing optimization techniques, including low-level microarchitecture-specific instruction scheduling, unused section elimination, and aggressive Link-Time Optimization (LTO).

Components

  • armclang:
    • Is built on modern LLVM and Clang technology
    • Supports GNU syntax assembly
    • Is highly compatible with source code originally written for GCC
    • Implements specifications including ANSI/ISO C and C++, ABI for the Arm architecture, ABI for the 64-bit Arm architecture, and Arm C Language Extensions (ACLE)

  • armlink: Feature-rich dedicated embedded linker that combines objects and libraries to produce an executable

  • Arm C libraries: Optimized by Arm for performance and code density, and include the tiny MicroLib for deeply embedded applications.

  • Arm C++ libraries: Libraries based on the LLVM libc++ project

  • fromelf: Image conversion utility and disassembler

  • armar: Archiver that enables sets of object files to be collected together

Use cases

Optimize resources icon black

Develop efficient software

From low-cost, memory-constrained embedded systems to high-end complex heterogeneous systems, Arm Compiler is optimized for a range of embedded workloads, with performance and code density that can be tuned for your specific target application.

Validated foundation icon black

Verify system design

Developed in collaboration with Arm processor and architecture projects, Arm Compiler is the ideal toolchain for verifying your design. Arm Compiler provides the earliest, most complete, and most accurate support for the latest Arm cores and architectural extensions.

Hardware icon black

Explore Arm architecture features

Selecting the right Arm IP is one of the most important decisions for your SoC design. Combined with Arm Flexible Access, Arm Compiler lets you evaluate which Arm solution best suits your application and market requirements.

Secuirty shield icon black

Build safety-critical code

Developing complex safety-related applications can be challenging and time-consuming. Specific releases of Arm Compiler and the C Libraries have been certified by TÜV SÜD for development to the most demanding Safety Integrity Levels (SIL), accelerating your certification process.

Security lock icon black

Develop for secure systems

Some critical systems, like Secure firmware, have specific security requirements. Arm Compiler lets you generate execute-only code, and securely interface between Secure and Non-secure software in systems that implement TrustZone for  Armv8-M.
