[jira] Created: (HARMONY-5413) [DRLVM][Interpreter] Interpreter
does not have write barrier support for generational GC
[DRLVM][Interpreter] Interpreter does not have write barrier support for generational GC
----------------------------------------------------------------------------------------
Key: HARMONY-5413
URL: https://issues.apache.org/jira/browse/HARMONY-5413
Project: Harmony
Issue Type: Improvement
Components: DRLVM
Environment: All
Reporter: Xiao-Feng Li
Priority: Critical
Attachments: 01-gen-semispace.patch
I am now enabling generational semispace GC as the default GC to replace current Harmony GCv5 (the new GC brings big performance boost). Unfortunately I found our interpreter doesn't fully support write barrier as JIT does. This makes the tests under interpreter mode easily fail. Since the new GC is critical for DRLVM performance, it would be desirable if the interpreter write barrier support could be enabled as soon as possible.
To use gen mode semispace GC, please apply the 01-gen-semispace.patch to gc_gen/ directory.
Thanks!
