 These built-in functions map to the respective machine
 instruction, i.e.@: @code{nop}, @code{sei}, @code{cli}, @code{sleep},
 @code{wdr}, @code{swap}, @code{fmul}, @code{fmuls}
 resp. @code{fmulsu}. The three @code{fmul*} built-ins are implemented
 as library call if no hardware multiplier is available.

+@defbuiltin{void __builtin_avr_delay_cycles (unsigned long @var{ticks})}
 Delay execution for @var{ticks} cycles. Note that this
 built-in does not take into account the effect of interrupts that
 might increase delay time. @var{ticks} must be a compile-time
 integer constant; delays with a variable number of cycles are not supported.

-@item char __builtin_avr_flash_segment (const __memx void*)
+@defbuiltin{char __builtin_avr_flash_segment (const __memx void*)}
 This built-in takes a byte address to the 24-bit
 @ref{AVR Named Address Spaces,address space} @code{__memx} and returns
 the number of the flash segment (the 64 KiB chunk) where the address
 points to.  Counting starts at @code{0}.
 If the address does not point to flash memory, return @code{-1}.

 Insert bits from @var{bits} into @var{val} and return the resulting
 value. The nibbles of @var{map} determine how the insertion is
 performed: Let @var{X} be the @var{n}-th nibble of @var{map}
