This isn't a D-specific question though, so gcc.godbolt.org
would allow you to test a wider range of backends.
I was wondering if compilers can optimize this:
uint foo3(uint a)
{
return a*!(a/5);
}
That actually gives the same results.
That is cool ! However, careful, division can stall the
pipeline.
No optimiser worth it's salt is going to emit a idiv instruction
there.
