tree.h (categorize_ctor_elements): Adjust prototype and add descriptive comment...
* tree.h (categorize_ctor_elements): Adjust prototype and add
descriptive comment, both in accordance with the interface change
described below.
* varasm.c (constructor_static_from_elts_p): New function.
Whether a constructor node is a valid static constant initializer
if all its elements are.
(initializer_constant_valid_p) <CONSTRUCTOR value>: Use it.
* output.h: Declare it.
* expr.c (categorize_ctor_elements_1): Return whether the constructor
is a valid constant initializer instead of computing the number of
non-constant elements. Use constructor_static_from_elts_p for this
purpose. Replace the head comment with an indication that this is a
helper for categorize_ctor_elements.
(categorize_ctor_elements): Same interface change as for the _1
helper. Former head comment from this helper moved here, adjusted to
account for the interface changes.
(mostly_zeros_p): Adjust call to categorize_ctor_elements.
(all_zeros_p): Likewise.
* gimplify.c (gimplify_init_constructor): Decide whether we can make
static versions of the constructor from the categorize_ctor_elements
return value instead of the formerly computed number of non-constant
elements.
* gnat.dg/outer_agg_bitfield_constructor.adb: New test.
* gnat.dg/nested_agg_bitfield_constructor.adb: New test.
