Subject: [Qemu-devel] [PATCH 07/14] exec.c: Add new address_space_ld*/st* functions
Date: Tue, 7 Apr 2015 21:09:53 +0100 [thread overview]
Message-ID: <1428437400-8474-8-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1428437400-8474-1-git-send-email-peter.maydell@linaro.org>
Add new address_space_ld*/st* functions which allow transaction
attributes and error reporting for basic load and stores. These
are named to be in line with the address_space_read/write/rw
buffer operations.
The existing ld/st*_phys functions are now wrappers around
the new functions.
