Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |build Component|bootstrap |libfortran Version|7.2.1 |8.0 Target Milestone|--- |8.0 --- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Actually there might be an issue here: typedef _Complex float __attribute__((mode(TC))) __complex128; in libgfortran/acinclude.m4 . Because IEEE 128bit uses KC while TC is used for IBM fortran long double. See PR 81848 which uses KC inside libquadmath rather than TC.
