    • PR libstdc++/87116 fix path::lexically_normal() handling of dot-dot · dd35da2c 
      Previously the logic that turned "a/b/c/../.." into "a/" failed to
preserve an empty path at the end of the iteration sequence, as required
by the trailing slash. That meant the result didn't meet the class
invariants, and that "a/b/c/d/../../.." would remove four components
instead of the three that "../../.." should remove.

	PR libstdc++/87116
	* src/filesystem/std-path.cc (path::lexically_normal): When handling
	a dot-dot filename, preserve an empty final component in the iteration
	sequence.
	[_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Use preferred-separator for
	root-directory.
	* testsuite/27_io/filesystem/path/generation/normal.cc: Add new tests
	for more than two adjacent dot-dot filenames.
	[_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Replace slashes with
	preferred-separator in expected normalized strings.

	PR fortran/80477
	* trans-expr.c (gfc_conv_procedure_call): Allocatable class
	scalar results being passed to a derived type formal argument
	are finalized if possible. Otherwise, rely on existing code for
	deallocation. Make the deallocation of allocatable result
	components conditional on finalization not taking place. Make
	the freeing of data components after finalization conditional
	on the data being NULL.
	(gfc_trans_arrayfunc_assign): Change the gcc_assert to a
	condition to return NULL_TREE.
	(gfc_trans_assignment_1): If the assignment is class to class
	and the rhs expression must be finalized but the assignment
	is not marked as a polymorphic assignment, use the vptr copy
	function instead of gfc_trans_scalar_assign.

	PR fortran/86481
	* trans-expr.c (gfc_conv_expr_reference): Do not add the post
	block to the pre block if the expression is to be finalized.
