Subject: [PULL 04/60] semihosting: Move softmmu-uaccess.h functions out of line
Date: Tue, 28 Jun 2022 10:23:07 +0530	[thread overview]
Message-ID: <20220628045403.508716-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220628045403.508716-1-richard.henderson@linaro.org>

Rather that static (and not even inline) functions within a
header, move the functions to semihosting/uaccess.c.
