Subject [jira] Updated: (HARMONY-3584) [drlvm][jit][opt] arraycopy folding implementation in guarded manner
Date Mon, 10 Sep 2007 07:02:29 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-3584?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dmitry Pronichkin updated HARMONY-3584:
---------------------------------------

    Attachment: arraycopy_pass.patch

Here is a patch carrying arraycopy optimization in the separate PMF pass. 

I have a question about the other two arracopy optimization methods: genArrayCopy and genCharArrayCopy.
What to do with them and with corresponding translation flags?

> the feature (arraycopy call replacement) can be done in the guarded manner. When the
classes of the arrays are being checked at runtime. 
> (It is not obvious if it gives a performance effect or not). 
> when this approach (guarded arraycopy call "inlining") is being implemented this optimisation
should be moved out from the translator and inserted (before inliner) into the HLO path as
a separate optimisation.
