From: Petar Jovanovic
Subject: [Qemu-devel] [PATCH] target-mips: remove wrong checks for recip.fmt and rsqrt.fmt
Date: Tue, 18 Aug 2015 19:35:29 +0200

From: Petar Jovanovic <address@hidden>

Instructions recip.{s|d} and rsqrt.{s|d} do not require 64-bit FPU neither
they require any particular mode for its FPU. This patch removes the checks
that may break a program that uses these instructions.
