I did look at https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libm/src/s_fma.c?annotate= =3D1.7 which is based on das@ code. This code does not have the special, but if I read it correctly would fall through to the subnormal case in the lines 174= -189 block of code with Victor's values. netbsd uses essentially freebsd's code with a few minor changes, so likely = has the same issue as in this bug report. --=20 You are receiving this mail because: You are the assignee for the bug.=
