[avr-libc-dev] [bug #28756] Bug in AVR libc 1.6.7 (power.h for 8-bit AVR)

[Joerg Wunsch]

Update of bug #28756 (project avr-libc):

                  Status:               Need Info => Confirmed

Follow-up Comment #13:

I can now see the problem with that code.  They stupidly
parenthesize the call to clock_prescale_set() within another
macro, like:


#define Set_cpu_prescaler(x) (clock_prescale_set(x))


While this is completely pointless for a function with void
return value (as it could never become part of an arithmetic
expression), it's still legal C code.

I guess the best solution then is to use an inlined function
rather than a macro to implement clock_prescale_set().
