Subject [jira] Created: (HARMONY-2247) System::arraycopy by 'rep move' instruction
Date Tue, 21 Nov 2006 06:12:02 GMT
System::arraycopy by 'rep move' instruction
-------------------------------------------

                 Key: HARMONY-2247
                 URL: http://issues.apache.org/jira/browse/HARMONY-2247
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
         Environment: ia32
            Reporter: George Timoshenko


Currenlty Jitrino::OPT instead of 'System::arraycopy' call generates a loop that copies arrays
with respective checks.

The improvements is in replacing the loop by 'rep move' instruction which is available on
ia32.
(This is possible as the instruction is now supported in Encoder. See the patch for HARMONY-2223)
