The process was pretty similar to the softmmu move except we take the time to split stuff between user.c and user-target.c to avoid as much target specific compilation as possible. We also start to make use of our shiny new header scheme so the user-only helpers can be included without the rest of the exec/gsbstub.h cruft. As before we split some functions into user and softmmu versions Reviewed-by: Fabiano Rosas <farosas@suse.de> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20230302190846.2593720-12-alex.bennee@linaro.org> Message-Id: <20230303025805.625589-12-richard.henderson@linaro.org>
