Of course it is ;) Before pointer-conversions became useless we didn't
propagate the invariant address into the OBJ_TYPE_REF expression.
We still have useful function-pointer conversions as well, because
dropping them would wreck CALL_EXPRs, too (we need to preserve the
original function type, similar to the alias-type on MEM_REFs).
I suppose we could do the same for OBJ_TYPE_REFs that I plan(ned) for
CALL_EXPRs - store the pointed-to type via a MEM_REF - thus a
You'd then have
CALL_EXPR (MEM [fnptr], args ...)
OBJ_TYPE_REF (MEM [fnptr], MEM [objptr], index)
where both TREE_TYPE of the function and the object are kept like the
FE specified them.
