Subject [jira] Commented: (HARMONY-1677) [drlvm][jitrino]MMTk-style magics implementation for Jitrino.JET compiler.
Date Fri, 06 Oct 2006 06:49:21 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1677?page=comments#action_12440350 ] 
            
Mikhail Fursov commented on HARMONY-1677:
-----------------------------------------

Weldon, I fixed isZero and toLong problems and going to commit the updated patch into the
JIRA in a hour or two

But I think that the following lines from the second and third test are incorrect:

res &= Extent.fromIntSignExtend(0xBABA).toLong() == 0xffFFffFFffFFBABAL;
res &= Extent.fromIntSignExtend(0xffffffff).toLong() == 0xFFffFFffFFffFFffL; 

Extent is 32-bit unsigned for IA32. So we ask to convert positive value to 'long' -> the
result must be positive too.
?
