--- Comment #1 from Uroš Bizjak <ubizjak at gmail dot com> ---
Adding clobbered registers explicitly is exactly the same as adding them to
call_fusage, so I don't see any problem here from the first sight.

Can you please provide a minimized testcase, following instructions at [1].
Unfortunately, I don't have access to Windows target, please provide a testcase
that fails on linux. You can decorate calls with __attribute__((ms_abi)) even
on linux.
