Subject: [PULL 1/7] linux-user/aarch64: Set siginfo_t addr field for SIGTRAP signals
Date: Fri, 24 Sep 2021 15:56:25 +0200	[thread overview]
Message-ID: <20210924135631.2067582-2-laurent@vivier.eu> (raw)
In-Reply-To: <20210924135631.2067582-1-laurent@vivier.eu>

From: Peter Maydell <peter.maydell@linaro.org>

When generating a TRAP_BRKPT SIGTRAP, set the siginfo_t addr field
to the PC where the breakpoint/singlestep trap occurred; this is
what the kernel does for this signal for this architecture.

Fixes: Coverity 1459154
