This was the way first C++ compilers operated.  GCC compiles C++ code directly into assembly.

Try searching for an old compiler that does this; beware, code may not be pretty or work reliably.  You can try LLVM, which, I think, compiles C++ into its internal representation, which you then can compile back to C.

Try -pipe compiler option.
