Subject: [PATCH v7 01/14] tcg: Reset data_gen_ptr correctly
Date: Mon, 21 Oct 2024 17:11:21 -0700	[thread overview]
Message-ID: <20241022001134.828724-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20241022001134.828724-1-richard.henderson@linaro.org>

This pointer needs to be reset after overflow just like
code_buf and code_ptr.
