Actually the compiler is correct here, this should be:
if ((fpscr >> i & 0x1) == 1) {
or even just
if (fpscr >> i & 1) {
because & is lower priority than == but the result may still be the
same by chance if 0x1 == 1 is always 1 and ANDing the shifted value
with this is either 0 or 1 so it may give the correct result but not
the way one would think looking at the expression.
I changed it to this:
if (((fpscr >> i) & 0x1) == 1)
Thank you.
