C++ at High Subsonic Speed
summary
KONGSBERG builds NSM and JSM missiles running C++ since 1995 on PowerPC targets (NSM <2GB RAM, JSM 16 cores on Integrity 11). Toolchain includes HiMake builds, shaman workspace manager, Green Hills and GCC compilers with annual GCC cadence, QA C++ and clang‑tidy modernize, Google Test, Uncrustify+AStyle formatting, and hardware tracing. Coding rules ban runtime heap usage after init and use bounded containers; a trace-guided change from copy to move yields a 50× speed-up and enforces no heap after startup constraints.
