	macros.
	* gcc-interface/decl.c (add_parallel_type_for_packed_array):
	Rename to associate_original_type_to_packed_array.  When
	-fgnat-encodings=minimal, set original packed array type as so
	instead of as a parallel type to the implementation type.  In
	this case, also rename the implementation type to the name of
	the original array type.
	(gnat_to_gnu_entity): Update invocations to
	add_parallel_type_for_packed_array.  Tag ARRAY_TYPE nodes for
	packed arrays with the TYPE_PACKED flag.
	When -fgnat-encodings=minimal:
	  - strip ___XP suffixes in packed arrays' names;
	  - set the debug type for padding records around packed arrays
	    to the packed array;
	  - do not attach ___XUP types as parallel types of constrained
	    array types.
	* gcc-interface/misc.c (gnat_print_type): Update to handle
	orignal packed arrays.
	(gnat_get_debug_type): Update to reject packed arrays
	implementation types.
	(get_array_bit_stride): New.
	(gnat_get_array_descr_info): Add packed arrays handling.
	* gcc-interface/utils.c (maybe_pad_type): When
	-fgnat-encodings=minimal, set the name of the padding type to
	the one of the original packed type, if any.  Fix TYPE_DECL
	peeling around the name of the input type.

    • DWARF: add a language hook for scalar biased types · 69c5f9d7 
      Front-ends like GNAT for Ada sometimes use biased encodings for integral
types.  This change creates a new language hook so that the bias
information can make it into the debugging information back-end and
introduces an experimental DWARF attribute to hold it.

gcc/ada/ChangeLog:

	* gcc-interface/misc.c (gnat_get_type_bias): New.
	(LANG_HOOKS_GET_TYPE_BIAS): Redefine macro to implement the
	get_type_bias language hook.

gcc/ChangeLog:

	* langhooks.h (struct lang_hooks_for_types): New get_bias_field.
	* langhooks-def.h (LANG_HOOKS_GET_TYPE_BIAS): New.
	(LANG_HOOKS_FOR_TYPES_INITIALIZER): Initialize the
	get_bias_field.
	* dwarf2out.c
	(base_type_die): In non-strict DWARF mode, invoke the
	get_type_bias language hook for INTEGER_TYPE nodes.  If it
	returns a bias, emit an attribute for it.
	(subrange_type_die): Change signature to handle bias.  If
	non-strict DWARF mode, emit an attribute for it, if one passed.
	(modified_type_die): For subrange types, invoke the
	get_type_bias langage hook and pass the bias to
	subrange_type_die.

    • DWARF: create a macro for max dimensions for array descr. lang. hook · 98088266 
      The array descriptor language hook can hold the description of a limited
number of array dimensions.  This macro will ease preventing overflow in
front-ends.

gcc/ada/ChangeLog:

	* gcc-interface/misc.c (gnat_get_array_descr_info): When the
	array has more dimensions than the language hook can handle,
	fall back to a nested arrays description.  Handle context-less
	array types.

gcc/ChangeLog:

	* dwarf2out.h (DWARF2OUT_ARRAY_DESCR_INFO_MAX_DIMEN): New macro.
	(struct array_descr_info): Use it for the dimensions array's
	size.
	* dwarf2out.c (gen_type_die_with_usage): Check that the array
	descr. language hook does not return an array with more
	dimensions that it should.

    • DWARF: describe Ada dynamic arrays as proper arrays · 24bd3c6e 
      gcc/ada/ChangeLog:

	* gcc-interface/decl.c (gnat_to_gnu_entity): When
	-fgnat-encodings-minimal, do not add ___XUP/XUT suffixes to type
	names and do not generate ___XA parallel types.
	* gcc-interface/misc.c (gnat_get_array_descr_info): Match fat
	and thin pointers and generate the corresponding array type
	descriptions.
