Subject: [Qemu-devel] [PATCH for 2.13 09/19] linux-user: move openrisc cpu loop to openrisc directory
Date: Mon, 26 Mar 2018 21:15:53 +0200	[thread overview]
Message-ID: <20180326191603.10217-10-laurent@vivier.eu> (raw)
In-Reply-To: <20180326191603.10217-1-laurent@vivier.eu>

No code change, only move code from main.c to
openrisc/cpu_loop.c.
