From e4e5cb4a54403558defb4669a8c64cbd67713e1e Mon Sep 17 00:00:00 2001 From: Ilya Leoshkevich Date: Tue, 5 Mar 2024 12:09:39 +0000 Subject: [PATCH] {linux,bsd}-user: Introduce get_task_state() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A CPU's TaskState is stored in the CPUState's void *opaque field, accessing which is somewhat awkward due to having to use a cast. Introduce a wrapper and use it everywhere.
