Hello.
I have considered all proposals on changing '__builtin_avr_delay_cycles'
builtin. Also has added '__builtin_avr_fmul*' builtins.
There is one thing that crosses my mind. A user would not only want a
void interrupt_enable (void)
uint8_t interrupt_disable (void)
but also a
void interrupt_restore (uint8_t)
In 99% of the cases interrupt_disable would be used, the user needs an
option to restore the interrupt flag to it's previous state.
This feature would also make the atomic access builtin set of GCC
functions reachable. See
http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Atomic-Builtins.html#Atomic-Builtins
for more detail.
