Subject: [PATCH v2 12/15] target/m68k: Fix stack frame for EXCP_ILLEGAL
Date: Thu, 2 Dec 2021 12:48:57 -0800 [thread overview]
Message-ID: <20211202204900.50973-13-richard.henderson@linaro.org> (raw)
In-Reply-To: <20211202204900.50973-1-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.
