Subject: [PATCH for-6.2 1/7] linux-user/aarch64: Set siginfo_t addr field for SIGTRAP signals
Date: Fri, 13 Aug 2021 14:18:03 +0100 [thread overview]
Message-ID: <20210813131809.28655-2-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210813131809.28655-1-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
