Subject: [PATCH v4 37/47] target/ppc: Remove xscmpnedp instruction
Date: Tue, 22 Feb 2022 11:36:35 -0300	[thread overview]
Message-ID: <20220222143646.1268606-38-matheus.ferst@eldorado.org.br> (raw)
In-Reply-To: <20220222143646.1268606-1-matheus.ferst@eldorado.org.br>

From: Víctor Colombo <victor.colombo@eldorado.org.br>

xscmpnedp was added in ISA v3.0 but removed in v3.0B. This patch
removes this instruction as it was not in the final version of v3.0.
