Subject: [PATCH v4 04/53] semihosting: Move softmmu-uaccess.h functions out of line
Date: Tue, 7 Jun 2022 13:45:08 -0700 [thread overview]
Message-ID: <20220607204557.658541-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220607204557.658541-1-richard.henderson@linaro.org>
Rather that static (and not even inline) functions within a
header, move the functions to semihosting/uaccess.c.
Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
