--- Comment #15 from Uroš Bizjak <ubizjak at gmail dot com> ---
Fixed by the revert.
The first problem, reported in Comment #0 was actually due to missing registers
in ix86_function_value_regno_p, so multi-register output was not properly
detected. This problem was fixed by [1].
The second problem was indeed due to missing output value copy, where the copy
insn was removed as useless move insn. This problem was fixed by a revert.
I have committed a couple of testcases that cover both issues.
