Subject: [PATCH 10/16] fix killing OP_CALL via pointers
Date: Thu, 16 Feb 2017 05:57:02 +0100 [thread overview]
Message-ID: <20170216045708.50661-11-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20170216045708.50661-1-luc.vanoostenryck@gmail.com>
When killing an OP_CALL corresponding to a function pointer
the ->func field needs also to have its usage adjusted.
