Colleagues,
I created a new JIRA issue with an improvement proposal for Jitrino.OPT.
https://issues.apache.org/jira/browse/HARMONY-5743
In compressed mode OPT always uncompress a ref just after it is loaded
from memory (from field).
So each reference is uncompressed in the managed code.
It is a convention in HLO. There are not dedicated instructions for
compression/uncompression.
IRBuilder generates LdField and its dst operand has type - UncompressedRef.
It probably has sense not to uncompress ref if it is loaded just for
NULL comparison or storing to another field.
To do this we need to generate Compress/Uncompress instructions
explicitly during byte code translation.
I almost completed this work.
Unfortunately it may happen I will have no ability to complete this work.
I will be happy to see somebody completed the task.
Thank you,
George.
