I just realized that I misremembered the TREE_PUBLIC patch: It has been
committed after 4.7 was branched (cf. PR40973 and PR40973 / PR52916). Thus, it
is not a regression.
Another, possibly related question is: Why is the function "hello_integer" not
inlined into its only user? The compiler does realize that the variable is
local as in the "nm" output the "t" shows and the ".constprop.0" suffix with
-O2/-O3/-Ofast:
0000000000000000 t __mod_say_hello_MOD_hello_integer.constprop.0
0000000000000080 T __mod_say_hello_MOD_say_hello
