For some low-level code it is sometimes useful to temporarily disable

interrupts.   Enabling/disabling interrupts manually can be error prone.  I

think it would be useful to have support for a function attribute that allows

the user to disable interrupts for individual functions.  There is already a

function attribute 'disinterrupt' that is used by the Epiphany and MeP target,

which could be re-used for this purpose.
