[Qemu-devel] [PATCH] target-mips: remove wrong checks for recip.fmt and rsqrt.fmt

[Petar Jovanovic]

From: Petar Jovanovic <petar.jovano...@imgtec.com>

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.
