Subject: [PATCH v6 01/14] tcg: Reset data_gen_ptr correctly
Date: Wed, 16 Oct 2024 12:31:27 -0700 [thread overview]
Message-ID: <20241016193140.2206352-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20241016193140.2206352-1-richard.henderson@linaro.org>
This pointer needs to be reset after overflow just like
code_buf and code_ptr.
