From a3fb396f2dc57f585a49091e12ec6c588c45e681 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Sat, 29 May 2021 03:26:32 +0200 Subject: [PATCH] MIPS/opcodes: Add TX39 CP0 register names The TX39 core has its distinct set of CP0 registers[1], so it needs a separate table to hold their names. Add a test case accordingly.
