It pretty much depends on if you are writing a research toy or plan to
sell the compiler. If you plan on selling it, triple all times you expect.
>From personal experience, I started writing a C compiler in 1982. 2 years
later, it was shipped (Datalight C). I have been working on it steadilly
ever since. It will never be finished.
A global optimizer takes 1 year to write, and then 1 year to debug out in
the field. Some companies never get it to work reliably :-).
A C compiler is about twice as complex as a Pascal compiler. C++ is twice
as complex as C. Starting from a working C compiler, it takes 1 to 2 years
to add C++ capability to it.
