Compiler, IDE and Debugger Toolchain Services

Compiler Toolchain Services

Ashling provide customised compiler toolchains tailored for your needs and requirements based on either the open-source GNU GCC or LLVM distributions along with the QEMU ISA simulator and debug support. For larger projects, we sometimes work together with our long-term partner Embecosm, an open-source software toolchain company.

Our expertise includes:

  • GNU GCC and LLVM toolchains including compiler, linker, assembler, binutils, run-time libraries and debuggers (GDB, OpenOCD, Eclipse CDT etc.).
  • Arm, MIPS, RISC-V and Synopsys ARC architecture support.
  • Improving optimization (i.e. code generation in terms of speed and code-size) of the toolchain at both a compiler and linker level.
  • Support for custom instructions (ISA extensions) including support in the compiler toolchain, QEMU ISA simulator and debuggers. See Ashling white paper on adding custom RISC-V instructions to QEMU here.
  • New run-time libraries and optimization of existing libraries.
  • Ensuring the toolchain is kept up to date with all other community updates (e.g. quarterly updates/releases).
  • Compliance, certification and qualification of the toolchain e.g. to ISO26262 and IEC61508 standards.
  • Testing, verification and bug-fixing of the toolchain on both software simulators and real target hardware.


Common Vulnerability Exploits

Ashling offer Common Vulnerability Exploits (CVEs) identification and remediation support. A CVE is a publicly disclosed security vulnerability that may exist in an open-source toolchain (e.g. the compiler) or the run-time target libraries. CVEs in run-time libraries are particularly problematic as they may end up also being present i.e. “linked-in” to the end-user’s target application. If required, we will take all reasonable steps to ensure CVEs are remediated (i.e. “patched and removed”) before releasing toolchain versions thus allowing you to provide a high-level of security to both your internally developed applications and those of your toolchain end-users.

IDE and Debugger Services

RiscFree™ is Ashling’s Eclipse-CDT based Integrated Development Environment (IDE) and Debugger which can be customised and tailored for your needs and requirements.
