Maciej W. Rozycki 2b5e869ecf MIPS: ELF: Interpret the NAN2008 file header flag ... Handle the EF_MIPS_NAN2008 ELF file header flag and refuse execution where there is no support in the FPU for the NaN encoding mode requested by a binary invoked. Ensure that the setting of the bit in the binary matches one in any intepreter used. Set the thread's initial FCSR contents according to the value of the EF_MIPS_NAN2008. Set the values of the FCSR ABS2008 and NAN2008 bits both to the same value if possible, to take the approach taken with existing FPU hardware into account. As of now all implementations have both bits hardwired to the same value, that is both are fixed at 0 or both are fixed at 1, even though the architecture allows for implementations where the amount of control implemented with each of these two individual bits is independent of each other.
