--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. The main reason is we do not track "memory" changes in debug.
But then we rewrite the initial assignment into SSA and after DCEing that
end up with a debug stmt for the initializer.
It also shows FRE could, as CCP, rewrite no longer address-taken locals
into SSA form. Or we could make DSE insert debug stmts for killing
stores of register type?
