Subject: [Qemu-devel] [PATCH v23 13/22] target/rx: Dump bytes for each insn during disassembly
Date: Sat, 17 Aug 2019 16:36:19 +0900
Message-ID: <20190817073628.94473-14-ysato@users.sourceforge.jp> (raw)
In-Reply-To: <20190817073628.94473-1-ysato@users.sourceforge.jp>

From: Richard Henderson <richard.henderson@linaro.org>

There are so many different forms of each RX instruction
that it will be very useful to be able to look at the bytes
to see on which path a bug may lie.
