Subject: [Qemu-devel] [PATCH 02/13] linux-user: Rename cpu_clone_regs to cpu_clone_regs_child
Date: Sun, 19 May 2019 13:19:42 -0700 [thread overview]
Message-ID: <20190519201953.20161-3-richard.henderson@linaro.org> (raw)
In-Reply-To: <20190519201953.20161-1-richard.henderson@linaro.org>
We will need a target-specific hook for adjusting registers
in the parent during clone. To avoid confusion, rename the
one we have to make it clear it affects the child.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
