The dragon book barely mentions SSA for example
In fairness, dmd doesn't use SSA either
That's not a good thing.
No, but if the OP's goal is to contribute to dmd, learning SSA
wouldn't be very helpful beyond a general acclimation to
compiler arcana.
(Unless they wish to add SSA to dmd--a worthy goal, but perhaps
not the best thing to start out with.)
The backend is not where our efforts should be going. There is
way too much work that needs doing above it to motivate working
on the backend. The backend's design for the most part is
extremely simple just buried under 40 years of code.
Besides, there's more to life than dmd, everything else is SSA at
least some point in compilation (i.e. GCC isn't SSA all the way
down but GIMPLE is).
