expr.c (expand_expr_real_1): Apply the big-endian adjustment for bit-fields to all aggregate types.
* expr.c (expand_expr_real_1) <BIT_FIELD_REF>: Apply the big-endian
adjustment for bit-fields to all aggregate types.
ada/
* gcc-interface/gigi.h (make_packable_type): Remove default value.
(value_factor_p): Tweak prototype.
* gcc-interface/decl.c (gnat_to_gnu_entity): Add comment.
(gnat_to_gnu_component_type): Likewise.
(gnat_to_gnu_field): Likewise. Fetch the position of the field earlier
and simplify the condition under which the type is packed. Declare
local variable is_bitfield. Pass 1 as max_align to make_packable_type
if it is set to true.
(copy_and_substitute_in_layout): Pass 0 to make_packable_type.
* gcc-interface/utils.c (make_packable_array_type): New function.
(make_packable_type): Use it to rewrite the type of array field.
(maybe_pad_type): Pass align parameter to make_packable_type.
(create_field_decl): Minor tweaks.
(value_factor_p): Assert that FACTOR is a power of 2 and replace the
modulo computation by a masking operation.
