Nope. I get an ICE for the following testcase:
real, parameter :: x0(1) = 0
real, parameter :: x(1) = (/ x0 /) + 1
end
The problem is that we come into gfc_arith_plus() with one operand being an
EXPR_ARRAY, so looking at its value.real is wrong (if you want to do something
with it, it's value.constructor that should be looked at). I guess
reduce_binary_ac() should really look deeper: in the loop "for (c = head; c; c
= c->next)", we should see whether c->expr is an EXPR_CONSTANT before calling
eval(), and look deeper into it if it's an EXPR_ARRAY. (Though it's the first
time I look at this code and array constructors, I might be misunderstanding it
all.)
