As I can see, ICF creates thunk to a localalias of foo.
At which please I should preserve addressable attribute?
Thanks,
Martin

Indeed, you are right.
Glad it's solved in 4.9.
Closing the bug, then.

--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Hmm, I think we may get confused by having ADDRESSABLE flag set because the
original function body took its address and it makes sense to clear it as
Martin suggest.
I am bit confused on why this leads to ICE - I think false positive on
ADDRESSABLE flag ought to make cgraphunit to introduce extra copy in:
if (nargs)
for (i = 1, arg = DECL_CHAIN (a); i < nargs; i++, arg = DECL_CHAIN
(arg))
{
tree tmp = arg;
if (!is_gimple_val (arg))
{
tmp = create_tmp_reg (TYPE_MAIN_VARIANT
(TREE_TYPE (arg)), "arg");
gimple stmt = gimple_build_assign (tmp, arg);
gsi_insert_after (&bsi, stmt, GSI_NEW_STMT);
}
vargs.quick_push (tmp);
}
that may later end up on stack and prevent call from being a tail call.
I see that later optimizers may not be able to optimize out the extra copy
simply because it is bit hard to do: one needs to verify that the original
location is dead and possibly may be rewritten by a callee.
I did not find any code that would prevent clearning ADDRESSABLE flag on
parameters, so I think Martin's patch is correct.
Additionally I think it is not safe to set TAILCALL flag if the code above
introduced a local variable. This is becuase setting this flag by hand bypasses
logic in suitable_for_tail_call_opt_p that prevents tail call conversion when
any ADDRESSABLE vars exists.
I did not find any reasons why ADDRESSABLE flag should be set on parameter
besides the usual case that it has address taken, so I tink Martin's patch is
OK and correct fix.
Martin, does it fix the other PR too?
