Subject: [PATCH] accel/tcg: Init tb size and icount before plugin_gen_tb_end
Date: Tue, 21 May 2024 14:06:04 -0700	[thread overview]
Message-ID: <20240521210604.130837-1-richard.henderson@linaro.org> (raw)

When passing disassembly data to plugin callbacks,
translator_st_len relies on db->tb->size having been set.

Fixes: 4c833c60e047 ("disas: Use translator_st to get disassembly data")
Reported-by: Bernhard Beschow <shentey@gmail.com>
