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)
