MIPS supports two different NaN encodings, legacy and 2008. Information about MIPS NaN encodings can be found here: https://sourceware.org/binutils/docs/as/MIPS-NaN-Encodings.html NaN legacy is the only option available for R2 cores and older. NaN 2008 is the only option available for R6 cores. R5 cores can have either NaN legacy or NaN 2008, depending on the implementation. So, if the user selects a generic R5 target architecture variant, we show a choice menu with both options available. For well known R5 cores we directly select the NaN enconding they use.
