Subject: [PULL 03/10] tcg: Optimize inline dup_const for MO_64
Date: Sat, 23 Jan 2021 08:50:13 -1000 [thread overview]
Message-ID: <20210123185020.1766324-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210123185020.1766324-1-richard.henderson@linaro.org>
Avoid the out-of-line function call for immediate MO_64.
In addition, diagnose all invalid constants at compile-time.
