Fortran: do not copy back for parameter actual arguments [PR81978]
When an array is packed for passing as an actual argument, and the array
has the PARAMETER attribute (i.e., it is a named constant that can reside
in read-only memory), do not copy back (unpack) from the temporary.
PR fortran/81978
gcc/fortran/ChangeLog:
* trans-array.cc (gfc_conv_array_parameter): Do not copy back data
if actual array parameter has the PARAMETER attribute.
* trans-expr.cc (gfc_conv_subref_array_arg): Likewise.
gcc/testsuite/ChangeLog:
* gfortran.dg/pr81978.f90: New test.
