kargl at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |FIXED --- Comment #6 from kargl at gcc dot gnu.org --- Fixed on trunk. The GFORTRAN_1.6 section of the symbol map where I've inserted the _gfortan_mvbits_i16 symbol does not exist in 5-branch. If the other functions in this section are backported, then this function can also be backported.
