I would just remove #ifdef and use extra shift always. One additional instruction will not affect performance but will guaranty the correctness since in 32-bit VM the upper bit of src register could be set also.

I looked on Nightly and the test passed:

Passed: compiler/6823354/Test6823354.java But they running on Niagara 1 machines which does not have popc so this code is not exercised.

Ahh, that explains it :-/
