@cindex @code{fast_interrupt} function attribute, MicroBlaze
These attributes indicate that the specified function is an interrupt
handler. Use the @code{fast_interrupt} attribute to indicate handlers
used in low-latency interrupt mode, and @code{interrupt_handler} for
interrupts that do not use low-latency handlers. In both cases, GCC
emits appropriate prologue code and generates a return from the handler
using @code{rtid} instead of @code{rtsd}.
