Subject: [PATCH v3 32/33] target/ppc/mmu-radix64.c: Drop a local variable
Date: Wed, 08 May 2024 02:15:26 +0200 (CEST) [thread overview]
Message-ID: <043208173865575e0148ad19b8a3b4e1a96f0c4c.1715125376.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1715125376.git.balaton@eik.bme.hu>
The value is only used once so no need to introduce a local variable
for it.
