I think we should place
if (current_function_decl && ix86_is_interrupt_p ())
{
for (i = 0; i < FIRST_PSEUDO_REGISTER; i++)
{
if (!STACK_REGNO_P (i) && !MMX_REGNO_P (i))

Sorry, I don't understand why we shouldn't preserve the red zone. The function
"foo", executing before the interrupt was called, used its red zone. If the
interrupt does not adjust the stack pointer, who

MMX instructions should be disallowed in interrupt handler:

Red zone isn't supported in interrupt handler:
'interrupt'
Use this attribute to indicate that the specified void function
without arguments is an interrupt handler. The compiler generates
