[avr-gcc-list] Is it possible to implement...

[Rune Christensen]

Hello

Is it possible to implement the following code in avr-gcc not using
assembler

if (carry(csumlo += data))
{
  if (carry(++csumhi))
  {
    csumlo++;
  }
}

Now it's implemented as

csumlo += data;
if (csumlo < data)
{
  if (++csumhi==0)
  {
    csumlo++;
  }
}

But I want to optimize it with the carry-bit

Thanks in advance
