Subject: [Qemu-devel] [PULL 02/34] softmmu: provide softmmu access type enum
Date: Mon, 3 Nov 2014 16:11:16 +0000	[thread overview]
Message-ID: <1415031108-15039-3-git-send-email-leon.alrae@imgtec.com> (raw)
In-Reply-To: <1415031108-15039-1-git-send-email-leon.alrae@imgtec.com>

New MIPS features depend on the access type and enum is more convenient than
using the numbers directly.
