MIPS: math-emu: Add support for the MIPS R6 MSUBF FPU instruction
MIPS R6 introduced the following instruction: Floating Point Fused Multiply Subtract: MSUBF.fmt To perform a fused multiply-subtract of FP values. MSUBF.fmt: FPR[fd] = FPR[fd] - (FPR[fs] x FPR[ft]) Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/10957/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
