Subject: [PATCH v3 13/30] target/ppc: Remove unnecessary gen_io_end calls
Date: Thu, 29 Apr 2021 18:15:26 -0700 [thread overview]
Message-ID: <20210430011543.1017113-14-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210430011543.1017113-1-richard.henderson@linaro.org>
Since ba3e7926691ed33, we switched the implementation of icount
to always reset can_do_io at the start of the following TB.
Most of them were removed in 9e9b10c64911, but some were missed.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
