Yours looks better.
It's unfortunate it can't work it out automatically like gcc can.
Anyway, you can write it out manually:
auto foo(ulong2 a, ulong2 l, ulong h)
{
static long2 shift = long.min; //-2^63
long2 aS = cast(long2)(a - shift);
long2 lS = cast(long2)(l - shift);
long2 hS = cast(long2)(h - shift);
return (hS > aS) & (lS > aS);
}
but that doesn't actually compile, the compiler just sits in
semantic3 forever (see
