--- Comment #5 from Kai Tietz <ktietz at gcc dot gnu.org> ---
Ok found issue. Problem is that x86_64 instructions have a maximum-offset of
2^31. Legitimate instruction doesn't detect here that constant is unsigned, so
it fails. Nevertheless issue would happen always too for (1U << 32) even for
x86_64 abi.
Solution might be here to use the eax-register for addressing instead of
constant.
