Softek Toolchains

Experts in tailor-made compiler toolchains and system libraries

Compiler Toolchains
Our Services

Access Softek can help you get the best possible software development tools tailored to your specific target. We can port and optimize your existing compiler, or develop it from scratch.

Our compiler development services include:

  • Full toolchain cycle R&D: compiler, linker, debugger, system libraries
  • Maintenance of the existing toolchain, catching up with the upstream releases and changes
  • Development of custom features, including compiler pragmas, language extensions, target-specific optimizations and more
  • Code security hardening

System libraries such as libc and libc++ are quite standard when facing toward applications. On the other hand, each of them requires some porting and tuning for a particular platform to be efficient.

We can help you with porting the system libraries or tuning them up for your platform.

  • C std library
  • C++ std library (supporting C++11, 14, 17 features)
  • Target-specific tuning

Having your platform officially supported by a large open source project like LLVM could save significant time and effort in adapting changes from upstream. There are certain requirements for getting a platform formally supported.

In some cases, it is easier and more secure to have us represent your target for the open source community. As an LLVM partner and active contributor, we know the procedures and practices that help minimize risk, time and effort.

This also might screen your involvement or interest in a particular architecture, or certain aspects of a to-be-announced platform.

A big part of quality software applications is having the right tools for identifying unsafe or non-optimal code constructions that are specific to a target platform. Some of these tools perform checks statically when compiling, while others must perform at run time.

In both cases the compiler can be of service in aiding the checkers and placing instrumentation points. It helps to have compiler-based tools made for specific tasks as a part of a modern toolchain.

  • Code analysis tools
  • Profiling and code coverage
  • PGO (needs target support) and LTO
