* ldmain.c (add_to_set): Now takes reloc argument rather than
bitsize. Check config.build_constructors here. If an new hash
table entry is created, mark it as undefined.
(constructor_callback): No longer takes bitsize argument. Pass
BFD_RELOC_CTOR to ldctor_add_set_entry, but first make sure the
BFD backend supports it.
(reloc_overflow): Handle a NULL abfd argument.
(reloc_dangerous, unattached_reloc): Likewise.
* ldctor.c: Include ldmain.h.
(struct set_info): Change bitsize field to reloc.
(ldctor_add_set_entry): Now takes reloc argument rather than
bitsize. Don't bother to check config.build_constructors here.
(ldctor_build_sets): Get the size from the reloc howto. If
generating relocateable output, call lang_add_reloc rather than
lang_add_data.
* ldctor.h (ldctor_add_set_entry): Change declaration to use reloc
instead of bitsize.
* ldlang.h (statement_enum): Add lang_reloc_statement_enum.
(lang_reloc_statement_type): New structure.
(lang_statement_union_type): Add reloc_statement field.
(lang_add_reloc): Declare new function.
* ldlang.c (lang_for_each_statement_worker): Handle
lang_reloc_statement_enum.
(map_input_to_output_sections, print_statement): Likewise.
(lang_size_sections, lang_do_assignments): Likewise.
(print_reloc_statement): New function.
(lang_add_reloc): New function.
* ldwrite.c (build_link_order): Handle lang_reloc_statement_enum.
