I'm asking this question coming from inspection of QBE IL generated
from cproc (bootstrap), so I might be completely misguided.

However, what is the purpose of eval.c?

From initial view it looks like many expression optimisations(?) that
are better left for QBE, or indeed are currently handled by QBE.

Ok, apologies, I see now that some level of constant expression
evaluation at compile time is necessary to impose C standards.
