Compiler-based runtime tools that detect bugs: memory errors, undefined behavior, data races, memory leaks. Much faster than Valgrind, part of GCC/Clang.

There is a tool that finds real defects, requires no new install, no configuration file, and no CI integration beyond a flag already accepted by the compiler you are already invoking on every build — and most projects run it in a mode that throws its findings away. That tool is the compiler itself. arm-none-eabi-gcc already builds a fully type-checked internal representation of your program to generate code from; a warning is analysis it already did, offered back to you, and the default build configuration in a great many embedded projects is -Wall at best, or nothing at all, which means the cheapest static analysis available is routinely left switched off.
