Subject [jira] Commented: (HARMONY-5621) [drlvm] Remove unsupported runtime helpers.
Date Fri, 21 Mar 2008 08:23:26 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5621?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581027#action_12581027
] 

Alexey Varlamov commented on HARMONY-5621:
------------------------------------------

Notes on the patch:
1) It makes sense to declare consts like MIN_INT/MIN_LONG and use them consistently;
2) Better to eliminate CHAR_ARRAYCOPY optimization at all instead of keeping temporary helper
on IPF. That is, Java translator should be fixed: see JavaByteCodeTranslator::invokestatic()
and JavaByteCodeTranslator::genCharArrayCopy().
BTW, there is a related HARMONY-3584, I'll look if we can merge these issues.
