[Bug fortran/43040] [lto] gfortran.dg/gamma_5.f90: Wrong code for call to gamma w/ -flto

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2010-02-12 11:07 -------
This is because the Fortran frontend has different DECL_FUNCTION_CODE for the
same builtins as the middle-end, so they get mixed up (in this case LGAMMA
and GAMMA).

This needs to be fixed.

I also see

  /* We define these separately as the fortran versions have different
     semantics (they return an integer type) */
  gfc_define_builtin ("__builtin_roundl", mfunc_longdouble[0],
                      BUILT_IN_ROUNDL, "roundl", true);
...

ugh.  You can't overload existing builtin names with different semantics.
The middle-end expects that of gcc/builtins.def.  For the above case
there exists BUILT_IN_LROUNDL.
