Fortran: Set the vptr of a class typed result.
PR fortran/90076
gcc/fortran/ChangeLog:
* trans-decl.cc (gfc_generate_function_code): Set vptr for
results to declared class type.
* trans-expr.cc (gfc_reset_vptr): Allow to provide the typespec
instead of the expression.
* trans.h (gfc_reset_vptr): Same.
gcc/testsuite/ChangeLog:
* gfortran.dg/class_76.f90: Add declared vtab occurrence.
* gfortran.dg/class_78.f90: New test.
