Subject: [PULL v2 10/12] target/arm: Use tcg_constant_i32() in gen_rev16()
Date: Tue, 2 Nov 2021 14:25:17 -0400 [thread overview]
Message-ID: <20211102182519.320319-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20211102182519.320319-1-richard.henderson@linaro.org>
From: Philippe Mathieu-Daudé <f4bug@amsat.org>
Since the mask is a constant value, use tcg_constant_i32()
instead of a TCG temporary.
