Yeah, me too. But fixing that is not so easy.
A start is to have a rigorous set of tests for this part of the
compiler. I know the compiler has a test suite but I don't know how much
of this particular code is covered.
With a rigorous set of tests one will feel more comfortable in
refactoring the code.
Then it just some hard work that will probably take some time. The first
thing would probably be to try to put everything platform specific in
one place. Ideally there would only be one set of if-def's.
If possible this can happen iteratively in several steps. When a
function needs to be changed refactor it as well to make it more clean.
Ideally we don't want to the new COFF backend to become a part of this mess.
