Subject: [PATCH v2 01/30] linux-user/aarch64: Set siginfo_t addr field for SIGTRAP signals
Date: Sat, 21 Aug 2021 20:55:08 -0700	[thread overview]
Message-ID: <20210822035537.283193-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210822035537.283193-1-richard.henderson@linaro.org>

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
