It's a bug. Two, actually.
1) a shift of zero should be optimized out by
the compiler; cinap has a change for this in
the works already. This fix should hide the
second bug.
2) a shift by a literal zero is miscompiled by
the assembler into a shift by 32, because
of a missed special case in the instruction.
encoding. I'm working on fixing the assembler.
