[PATCH v3 2/5] target/arm: Introduce store_cpu_field_constant() helper |
Date: |
Sat, 30 Oct 2021 01:18:31 +0200 |
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).
