[PULL 03/29] {linux,bsd}-user: Introduce get_task_state() |
|
Date: |
Wed, 6 Mar 2024 14:40:15 +0000 |
From: Ilya Leoshkevich <iii@linux.ibm.com>
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.
