Do you believe this is impossible? It's really not, because some people do it. See yourself:

Writing source code directly in assembly language may make your code faster, as you can write the CPU instructions directly, making some critical optimization faster than the compiler-generated code.
Of course, the statement above about speed is false, and sometimes it's hard to write a faster code than the compiler generates. And, as you can see, the submissions just contain the code generated by the compiler instead of being written manually.
Oh
Do it make faster???
Can I solve problems, which directed to $$$O(n \cdot log(n))$$$ solution, by $$$O(n^2)$$$?
I will be more powerful if learn assembler!!!
sometimes yes
Sir, but maybe the user just wants to write 700 lines of code just for fun; who doesn't like writing assempbly for CP????
There're something like those in the code:
or
Those are the behavior of a C++ compiler, namely, GCC, those
_Z*
stuff are name mangling.
