+
+ Changes to make -Ur work again.
+ * 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.
+
+ * Makefile.in (cdtest.out, cdtest-ur.o): New targets.
+ (cdtest-ur, cdtest-ur.out): New targets.
+ (check-cdtest): Now also check that -Ur works correctly.
+
+ * scripttemp/alpha.sc: Align all sections to 16 byte boundaries.
+
+Thu Mar 17 12:45:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
+
+ * ldlang.c (lang_process): Move lang_common call before
+ map_input_to_output_sections, to ensure that any alignment
+ constraints set by common symbols are copied over to the output
+ sections.
+
+Fri Mar 11 22:17:34 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
+
+ * emulparams/elf32ppc.sh (TEMPLATE_NAME): Don't define.
+ (OTHER_READWRITE_SECTIONS): Rename .toc to .got.
+ * Makefile.in (em_elf32ppc.c): Depend upon generic.em, not ppc.em.
+ * emultempl/ppc.em: Remove ugly stub code; turns out not to be
+ needed for ELF.
