Subject: Re: How to debug ssa optimizer

    Maybe the canonical form for "char *foo, bar[10]; foo = bar;"
    should be 
    <modify_expr <var_decl foo>  <nop_expr type <char *> <var_decl bar>>
    instead of using addr_expr?

Well, the address is being taken, so I'd like to see ADDR_EXPR
someplace there.  For aliasing concerns, among others.
