The patch in ix86_function_arg_regno_p and
ix86_function_value_regno_p changes the number of registers used
to pass function parameters, and the number of registers used to
pass function return values. This violates the calling convention
on x86 Mac OS platform, and binary compatibility can no longer be
maintained.
You need comments in the patch about why we're doing something
different for OS X just like you'd comment any other piece of code.
