Hi all,

Apologies for such a basic question. I am trying to write an ISR on a
MPC551x. When I tried to use the interrupt attribute with
powerpc-eabi-gcc such as

_attribute_((interrupt_handler)) foobarISR(void)
{
}


it complains of a syntax error. Upon further investigation in the GCC,
it appears that the interrupt attribute is not supported by
powerpc-eabi-gcc.

Am I missing something fundamental here? How are the current interrupt
service routines created at the moment?

Any pointers would be appreciated.
