Hi,
Is there somebody who is able to give me a hint, how to manage it to pass
register passed arguments in two different registers ? I need this for the
x86_64 port. The MS ABI passes floating-points in XMM registers, but
additionally for va-sake within the standard integer registers as shadows.
Is there in gcc an example, which may can help ?
Regards,
i.A. Kai Tietz
