Subject: [Qemu-devel] [PULL 06/16] target-ppc: Split out SREGS get/put functions
Date: Wed, 16 Mar 2016 16:06:58 +1100 [thread overview]
Message-ID: <1458104828-32541-7-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1458104828-32541-1-git-send-email-david@gibson.dropbear.id.au>
Currently the getting and setting of Power MMU registers (sregs) take up
large inline chunks of the kvm_arch_get_registers() and
kvm_arch_put_registers() functions. Especially since there are two
variants (for Book-E and Book-S CPUs), only one of which will be used in
practice, this is pretty hard to read.
This patch splits these out into helper functions for clarity. No
functional change is expected.
