It's more a question of what makes sense vs what is gimple in this
case :-)  You can't change the address of an object, which is in
effect what you'd be trying to do if an ADDR_EXPR as on the LHS of
an assignment.

Anyway, I've bootstrapped and re-run the testsuite with just the
change to "see through" ADDR_EXPRs in the RHS of the use statement.
All is well and good.

I've attached the actual patch I installed.

Thanks,
Jeff
