[jira] Created: (HARMONY-2806) [drlvm][jit][opt] Simplifier does
not optimize loading of fun addr slot of known type
[drlvm][jit][opt] Simplifier does not optimize loading of fun addr slot of known type
-------------------------------------------------------------------------------------
Key: HARMONY-2806
URL: http://issues.apache.org/jira/browse/HARMONY-2806
Project: Harmony
Issue Type: Improvement
Components: DRLVM
Reporter: Pavel Ozhdikhin
Priority: Minor
Simplifier does not optimize ldvfnslot->ldfnslot when VTable load instruction has been simplified before (ldvtable->getvtable). The attached patch enables such optimization thus allowing further simpification of virtual call to a direct call.
The patch has been tested on Win32/debug/SPECjbb2005 only.
