[avr-gcc-list] optimzed division ?

[Eckhard Tikwinski]

Hi everyone,

is it a bug or is it a feature ?
I tried with gcc 2.97 and -O2:

int x;
x=0x7FFF;
x=x div 2; // will be optimized to shift

The generated code will increment x first if 
positive. Then it does an arithmetic shift. For 
x=0x7FFF the result will be 0xC000. Maybe this 
was inteded to do some kind of rounding.

Thanks,
