What is your goal? Writing a compiler, for fun and educational
purposes, or to implement a new language?
When the actual language is the main purpose and your language will be
a functional one you can try to piggyback on existing compilers.
For example, translate your language to the GHC core or UHC core
and you get a cross platform highly optimizing compiler for free. You
can now freely focus on the semantics of your language and let an
existing code generator do the dirty work for you.
When, in the end when your languages is finished, the existing
compiler is not fast enough, improve it and everyone benefits!
