[drlvm][em64t][jit] JIT does not include 'this' operand into GC enumeration for synchronized methods
----------------------------------------------------------------------------------------------------
Key: HARMONY-3389
URL: https://issues.apache.org/jira/browse/HARMONY-3389
Project: Harmony
Issue Type: Bug
Components: DRLVM
Reporter: Mikhail Fursov
Attachments: this.fix
JIT does not include 'this' operand into GC enumeration for synchronized methods on EM64T.
The cause is spilling of register (this) opnd in "copy expansion" pass and ignoring the newly created operand in IA32IRManager::calculateLivenessInfo, so usually 'this' opnd is considered as dead and is not reported to GC.
