Subject: [PULL 01/34] common-user/host/sparc64: Fix safe_syscall_base
Date: Fri, 11 Feb 2022 12:30:26 +1100	[thread overview]
Message-ID: <20220211013059.17994-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220211013059.17994-1-richard.henderson@linaro.org>

Use the "retl" instead of "ret" instruction alias, since we
do not allocate a register window in this function.

Fix the offset to the first stacked parameter, which lies
beyond the register window save area.

Fixes: 95c021dac835 ("linux-user/host/sparc64: Add safe-syscall.inc.S")
