Subject: Re: [Qemu-devel] [PATCH 02/15] monitor.c: Use ld*_p() instead of ld*_raw()
Date: Thu, 15 Jan 2015 15:54:32 +0000	[thread overview]
Message-ID: <871tmw2g5j.fsf@linaro.org> (raw)
In-Reply-To: <1421334118-3287-3-git-send-email-peter.maydell@linaro.org>


Peter Maydell <peter.maydell@linaro.org> writes:

> The monitor code for doing a memory_dump() was using ld*_raw() to do
> target-CPU accesses out of a local buf[] array. The correct functions
> for this purpose are ld*_p(), which take a host pointer, rather than
> ld*_raw(), which take an integer representing a guest address and
> are somewhat meaningless in softmmu configurations. Nobody noticed
> because for softmmu the _raw functions are the same as ldl_p but
> with some extra casts thrown in. Switch to using the correct functions
> instead.
