[Qemu-devel] [PATCH v3 28/50] target/sh4: fetch code with translator_ld


From: Alex Bennée
Subject: [Qemu-devel] [PATCH v3 28/50] target/sh4: fetch code with translator_ld
Date: Fri, 14 Jun 2019 18:11:38 +0100

From: "Emilio G. Cota" <address@hidden>

There is a small wrinkle with the gUSA instruction. The translator
effectively treats a (known) gUSA sequence as a single instruction.
For the purposes of the plugin we end up with a long multi-instruction
qemu_plugin_insn.

If the known sequence isn't detected we shall never run this
translation anyway.
