Subject: [Qemu-devel] [PATCH] linux-user/signal.c: Use frame->retcode instead of frame address for alpha target restorer
Date: Tue, 29 Mar 2016 22:01:45 +0800 [thread overview]
Message-ID: <1459260105-5536-1-git-send-email-chengang@emindsoft.com.cn> (raw)
From: Chen Gang <chengang@emindsoft.com.cn>
The restorer needs the return code address which is frame->retcode, not
frame itself.
