You can definitely generate intermediate code directly. I've seen
compilers that do it, but it's not something that I recommend. You may
think it will speed up your compilation or save you work, but it's not
measurably faster and it especially complicates optimizations and the
linking together of conditional branching code.


Separate your compiler into sensible parts.
