From 2a2105a26219695c72bfc7cab9b7d37754fc0920 Mon Sep 17 00:00:00 2001 From: Jiaxun Yang Date: Wed, 2 Nov 2022 16:57:18 +0000 Subject: [PATCH] target/mips: Don't check COP1X for 64 bit FP mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some implementations (i.e. Loongson-2F) may decide to implement a 64 bit FPU without implementing COP1X instructions. As the eligibility of 64 bit FP instructions is already determined by CP0St_FR, there is no need to check for COP1X again.
