--- Comment #9 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
I can reproduce it with gcc-10.2. Why is main 'overwritable', but foo is
'available'?

cat /tmp/cchaUSjV.ltrans0.o.079i.inline

;; Function main (main, funcdef_no=3D0, decl_uid=3D4385, cgraph_uid=3D1,
symbol_order=3D1) (executed once)

weakdef.c:5:5: note: Inlining foo/0 to main/1 with frequency 1.00
foo/0 (foo) @0x7f51a512d168
  Type: function definition analyzed
  Visibility: preempted_reg external public weak
  References:
  Referring:
  Function foo/0 is inline copy in main/1
  Availability: available
  Unit id: 2
