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