Subject: [PATCH v2 04/15] target/ppc: Do not call hreg_compute_mem_idx after ppc_store_msr
Date: Fri, 12 Mar 2021 19:00:07 -0600 [thread overview]
Message-ID: <20210313010018.819153-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210313010018.819153-1-richard.henderson@linaro.org>
In ppc_store_msr we call hreg_compute_hflags, which itself
calls hreg_compute_mem_idx. Rely on ppc_store_msr to update
everything required by the msr update.
