[jira] Commented: (HARMONY-5503) [drlvm][encoder] 128bit size support for encoder

["Dmitry Pronichkin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-5503?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568513#action_12568513 ] 

Dmitry Pronichkin commented on HARMONY-5503:
--------------------------------------------

There are some problems still:
1. Encoder's hash table size increasing. It can be solved only by hashing scheme rewriting.
2. Many instructions walk around the problem and changing them to normal mode will break JIT codegen.
3. LIR should be improved to work with 128bit types.

> Currently encoder doesn't support 128bit size operands. Instructions using such operands should walk around this problem passing 64bit operands to encoder. The patch introduces 128bit size support.
