Subject: [PATCH v2 11/30] linux-user/alpha: Use force_sig_fault, force_sigsegv_code
Date: Sat, 21 Aug 2021 20:55:18 -0700 [thread overview]
Message-ID: <20210822035537.283193-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210822035537.283193-1-richard.henderson@linaro.org>
Use the new functions instead of setting up a target_siginfo_t
and calling queue_signal.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
