Subject: [PATCH 09/14] linux-user/sparc: Handle priviledged opcode trap
Date: Wed, 1 Feb 2023 14:51:59 -1000 [thread overview]
Message-ID: <20230202005204.2055899-10-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230202005204.2055899-1-richard.henderson@linaro.org>
For the most part priviledged opcodes are ifdefed out of the
user-only sparc translator, which will then incorrectly produce
illegal opcode traps. But there are some code paths that
properly raise TT_PRIV_INSN, so we must handle it.
