Um... I don't know what to tell you - but I do that every day. Guess what - people who make libraries for other embedded devices, sometimes still write in assembly. Insane, I know.
You seem to be purposely ignoring what I am saying so that you contradict something I didn't say. I doubt people are writing the software for medical devices by directly writing to stack registers (which wouldn't mean the typical automatic instructions that push and pop the stack while automatically incrementing or decrementing the instruction pointer at the same time)
Your first comment didn't mention assembly. You only talked about C. It's insane that you switch the topic of the conversation and then pretend to be the only smart one.
