Subject: [PATCH v3 09/17] target/m68k: Fix stack frame for EXCP_ILLEGAL
Date: Tue, 15 Mar 2022 22:58:32 -0700	[thread overview]
Message-ID: <20220316055840.727571-10-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220316055840.727571-1-richard.henderson@linaro.org>

According to the M68040 Users Manual, section 8.4.3, Four word
stack frame (format 0), includes Illegal Instruction.  Use the
correct frame format, which does not use the ADDR argument.
