	  The Ingenic XBurst is a MIPS32R2 microprocessor. It has a
	  bug in the FPU that can generate incorrect results in
	  certain cases. The problem shows up when you have several
	  fused madd instructions in sequence with dependant
	  operands. This requires the -mno-fused-madd compiler option
	  to be used in order to prevent emitting these instructions.
