Description Andrew Cagney 2007-11-02 16:17:24 UTC

I.e., allow array ops with pointers (and conversely) pointer ops on arrays vis:

print array[0]
print *array
print *pointer
print pointer[0]

Comment 1 Teresa Thomas 2007-11-05 20:02:00 UTC

Dereferencing arrays with * requires word size, word size passed to ALU from
expression evaluator.

Commit:

Implement *(array + index), Call add(), plusEquals() directly from expression
evaluator.
