I think it's fascinating that we talk about systems written in C when
the code is produced by pass-0 in tool-chain where the last
pass consists of of a call to a traditional compiler.
What would be interesting to know is in what language did the engineers
put their intellectual effort,
If the automated tool chain is:
"C -> Assembly -> MachineCode"
"Ada -> Assembly -> MachineCode"
"Ada -> C -> Assembly -> MachineCode"
"simulink -> C -> Assembly -> MachineCode"
"simulink -> Ada -> C -> Assembly -> MachineCode"
All the above scenarios are possible so in what language is the system
written in ??
