From 6513ca15d8f4034bbc1b68a2cae4f54858fab61e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 26 Nov 2020 11:55:46 +0100 Subject: target/mips: Convert Rel6 CACHE/PREF opcodes to decodetree MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CACHE/PREF opcodes have been removed from the Release 6. Add a single decodetree entry for the opcodes, triggering Reserved Instruction if ever used. Remove unreachable check_insn_opc_removed() calls.
