[PATCH 7/9] target/mips: Remove microMIPS BPOSGE32 / BPOSGE64 unuseful c


From: Philippe Mathieu-Daudé
Subject: [PATCH 7/9] target/mips: Remove microMIPS BPOSGE32 / BPOSGE64 unuseful cases
Date: Thu, 17 Jun 2021 19:43:21 +0200

These switch cases for the microMIPS BPOSGE32 / BPOSGE64 opcodes have
been added commit 3c824109da0 ("target-mips: microMIPS ASE support").
More than 11 years later it is safe to assume there won't be added
soon. The cases fall back to the default which generates a RESERVED
INSTRUCTION, so it is safe to remove them.
