"Out of curiosity… what are Rust..." <- ChatGPT tells me: 1. **Diab Compiler by Wind River**: This compiler is safety-compliant and certified by TÜV SÜD for developing safety-related software. It is designed to help customers working on products that need to meet their end product's safety certification requiremens. 2. **Green Hills Software**: The Green Hills Compilers are certified to meet the highest levels of tool qualification and C/C++ runtime certification. They are qualified for SIL 4 and ASIL D, with pre-certified C/C++ runtime to the highest levels achievable. These compilers are supported on various platforms including 32- and 64-bit Arm and AURIX™ TriCore™ and can be run on Windows and Linux development environments. 3. **TASKING ARM Cortex-M Software Development Toolset**: This toolset provides complete C/C++ compiler support for all of the latest Cortex microcontrollers and is in compliance with industry-standard safety regulations including ISO26262 up to ASIL D. Their toolchain is certified by TÜV Nord according to the safety standards. These compilers are comparable to the Rust-based Ferrocene compiler, which has been qualified for use in safety-critical environments, being usable for systems up to ASIL D – the highest classification of initial hazard as defined by the ISO 26262 standard【77†source】. These proprietary compilers are equipped to develop software that must adhere to stringent safety standards, similar to Ferrocene's certification for Rust.
