Joseph Myers 525f803984 Add fmaxmag, fminmag functions. ... TS 18661-1 defines fmaxmag and fminmag functions that return the argument with maximum / minimum magnitude (acting like fmax / fmin if the arguments have the same magnitude or either argument is a NaN). These correspond to the IEEE 754-2008 operations maxNumMag and minNumMag. This patch implements these functions for glibc. They are implemented with type-generic templates. Tests are based on those for fmax and fmin. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (fmaxmag): New declaration. (fminmag): Likewise. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (fmaxmag): New macro.
