Subject: [PATCH v3 2/5] target/arm: Introduce store_cpu_field_constant() helper
Date: Sat, 30 Oct 2021 01:18:31 +0200 [thread overview]
Message-ID: <20211029231834.2476117-3-f4bug@amsat.org> (raw)
In-Reply-To: <20211029231834.2476117-1-f4bug@amsat.org>
Similarly to the store_cpu_field() helper which takes a TCG
temporary, store its value to the CPUState, introduce the
store_cpu_field_constant() helper which store a constant to
CPUState (without using any TCG temporary).
Suggested-by: Richard Henderson <richard.henderson@linaro.org>
