--- Comment #6 from HaoChen Gui <guihaoc at gcc dot gnu.org> --- gcc -O0 -fsignaling-nans -D_WANT_SNAN -lm -o main main.c && ./main (nan, 3.0), fmin: 3.0, builtin: 3.0, xsmincdp: 3.0, xsmindp: 3.0 (3.0, nan), fmin: 3.0, builtin: nan, xsmincdp: nan, xsmindp: 3.0 (snan, 3.0), fmin: nan, builtin: 3.0, xsmincdp: 3.0, xsmindp: nan (3.0, snan), fmin: nan, builtin: snan, xsmincdp: snan, xsmindp: nan (snan, snan), fmin: nan, builtin: snan, xsmincdp: snan, xsmindp: nan For 'fmin', the result is qnan if either argument is snan. The result of 'xsmindp' matches 'fmin'. I will make patch to implement fmin_optab by xsmindp and fmax_optab by xsmaxdp. Thanks.
