Subject: [Qemu-devel] [PATCH for 2.13 07/19] linux-user: move mips/mips64 cpu loop to mips directory
Date: Mon, 26 Mar 2018 21:15:51 +0200 [thread overview]
Message-ID: <20180326191603.10217-8-laurent@vivier.eu> (raw)
In-Reply-To: <20180326191603.10217-1-laurent@vivier.eu>
No code change, only move code from main.c to
mips/cpu_loop.c.
Include mips/cpu_loop.c in mips64/cpu_loop.c
to avoid to duplicate code.
