Problem with accessing built-ins from Fortran front-end

2014-09-26 Thread FX
Hi, I’m trying to make the Fortran front-end emit calls to some builtins we don’t currently use (isfinite, isnormal). However, trying to use the same code as isnan doesn’t work at all. Our gfc_define_builtin does three things: decl = add_builtin_function (name, type, code, BUILT_IN_NORMAL, li
