Subject: [PATCH v5 28/43] tcg/ppc: Use tcg_out_mem_long to reset TCG_REG_TB
Date: Tue, 5 Jan 2021 07:19:35 -1000 [thread overview]
Message-ID: <20210105171950.415486-29-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210105171950.415486-1-richard.henderson@linaro.org>
The maximum TB code gen size is UINT16_MAX, which the current
code does not support. Use our utility function to optimally
add an arbitrary constant.
