Subject: [PATCH 12/14] linux-user/sparc: Handle unimplemented flush trap
Date: Wed, 1 Feb 2023 14:52:02 -1000 [thread overview]
Message-ID: <20230202005204.2055899-13-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230202005204.2055899-1-richard.henderson@linaro.org>
For sparc64, TT_UNIMP_FLUSH == TT_ILL_INSN, so this is
already handled. For sparc32, the kernel uses SKIP_TRAP.
