assembly, C, and C++ is one of the most "standard" things to do out there. Unless you are talking about non-standard toolchains of course (everything that isn't clang or gcc based). C++ is mostly a superset of C so all the C++ compilers out there have pure C modes, and assembly integrates really well into C and C++ build systems.
