Do you have a test case to show this issue?

The last 3 interrupt control functions expect immediates as operands
in the inline assembly. That can only work if you pass compile time
constants as parameters, and that can only be figured out if the
function is inlined on every call. See also the svn history of that
file and how I got trapped by -O0, as those function break.
Best regards.
I forgot to mention: the functions as of now don't have the
always_inline attribute, but of course I was trying that so it would
work with -O0 but it didn't.
