[Hum... I think you mean -fno-math-errno.] gfortran doesn't have a need for errno to be set after math functions are called. However, we do want that have "correct" results in all cases: Inf, NaN, subnormals, etc. From my reading of the manual, -fno-math-errno would imply that we do not get such correct results, am I right? -- fxcoudert at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kargl at gcc dot gnu dot org Last reconfirmed|2006-10-22 21:01:38 |2006-10-25 08:19:20 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24518
