Subject [jira] Commented: (HARMONY-2325) [drlvm][jit][opt] Inst::getPureDefProperty method works incorrectly with extended instruction form

Nikolay Sidelnikov commented on HARMONY-2325:
---------------------------------------------

1) I have no regression test; this bug was reported by Pavel Ozhdikhin during some experiments.

2) I've check this patch on Win32 platform, debug/opt mode on SPECjbb2005 and kernel tests

3) Instruction with "PureDefProperty" and more then two source operands is an error
