The original version +of the standard did not specify how these two types should be +distinguished. Most implementations followed the i387 model, in which +the first bit of the significand is set for quiet NaNs and clear for +signalling NaNs. However, the original MIPS implementation assigned the +opposite meaning to the bit, so that it was set for signalling NaNs and +clear for quiet NaNs. + +The 2008 revision of the standard formally suggested the i387 choice +and as from Sep 2012 the current release of the MIPS architecture +therefore optionally supports that form. Code that uses one NaN encoding +would usually be incompatible with code that uses the other NaN encoding, +so MIPS ELF objects have a flag (@code{EF_MIPS_NAN2008}) to record which +encoding is being used. + +Assembly files can use the @code{.nan} directive to select between the +two encodings. @samp{.nan 2008} says that the assembly file uses the +IEEE 754-2008 encoding while @samp{.nan legacy} says that the file uses +the original MIPS encoding.
