Subject: [PATCH v3 04/16] target/ppc: Do not call hreg_compute_mem_idx after ppc_store_msr
Date: Sun, 14 Mar 2021 11:58:54 -0600	[thread overview]
Message-ID: <20210314175906.1733746-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210314175906.1733746-1-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.
