* doc/gnat_rm/implementation_defined_attributes.rst
(Scalar_Storage_Order): Adjust restriction for packed array types. * einfo.ads (Is_Bit_Packed_Array): Adjust description. (Is_Packed): Likewise. (Is_Packed_Array_Impl_Type): Likewise. (Packed_Array_Impl_Type): Likewise. * exp_ch4.adb (Expand_N_Indexed_Component): Do not do anything special if the prefix is not a packed array implemented specially. * exp_ch6.adb (Expand_Actuals): Expand indexed components only for bit-packed array types. * exp_pakd.adb (Install_PAT): Set Is_Packed_Array_Impl_Type flag on the PAT before analyzing its declaration. (Create_Packed_Array_Impl_Type): Remove redundant statements. * freeze.adb (Check_Component_Storage_Order): Reject packed array components only if they are bit packed. (Freeze_Array_Type): Fix logic detecting bit packing and do not bit pack for composite types whose size is multiple of a byte. Create the implementation type for packed array types only when it is needed, i.e. bit packing or packing because of holes in index types. Make sure the Has_Non_Standard_Rep and Is_Packed flags agree. * gcc-interface/gigi.h (make_packable_type): Add MAX_ALIGN parameter. * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Signed_Integer_Subtype>: Call maybe_pad_type instead of building the padding type manually. (gnat_to_gnu_entity) <E_Array_Subtype>: Do not assert that Packed_Array_Impl_Type is present for packed arrays. (gnat_to_gnu_component_type): Also handle known alignment for packed types by passing it to make_packable_type. * gcc-interface/utils.c (make_packable_type): Add MAX_ALIGN parameter and deal with it in the array case. Adjust recursive call. Simplify computation of new size and cap the alignment to BIGGEST_ALIGNMENT. From-SVN: r236279
