--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, on trunk it hides with r239421 (and -fcode-hoisting).

The problematic do_SUBST is:

(gdb) p debug_rtx(*into)
(reg:SI 202)
$1 = void
(gdb) p debug_rtx(newval)
(const_int 2147418112 [0x7fff0000])

Adding port maintainers to CC.
