Subject: [PULL 13/14] linux-user/sparc: Don't restore %g7 in sparc64_set_context()
Date: Fri, 18 Dec 2020 11:24:06 +0100 [thread overview]
Message-ID: <20201218102407.597566-14-laurent@vivier.eu> (raw)
In-Reply-To: <20201218102407.597566-1-laurent@vivier.eu>
From: Peter Maydell <peter.maydell@linaro.org>
The kernel does not restore the g7 register in sparc64_set_context();
neither should we. (We still save it in sparc64_get_context().)
