Hello!
This might not apply to g++ 4.1.2, which is what you use, but I
don't have this version right here to test it. It works fine for
gentoo's g++ 4.1.1 and produces no warnings:
template <int a>
int shift (int b)
{
if (a > 0) {
unsigned ua = a;
return b >> ua;
} else {
unsigned ua = -a;
return b << ua;
}
}
template int shift<1>(int);
template int shift<-1>(int);
However, you will have to turn on optimization in order to get the
same efficient code than with your version (x86 here).
(I do get a warning for converting -1 to unsigned on g++ 3.4.6)
