include/coff/
* xcoff.h (XCOFF_CALLED, XCOFF_IMPORT): Update comments. (XCOFF_WAS_UNDEFINED): New flag. (xcoff_link_hash_table): Add an "rtld" field. bfd/ * coff-rs6000.c (xcoff_ppc_relocate_section): Report relocations against undefined symbols if the symbol's XCOFF_WAS_UNDEFINED flag is set. Assert that all undefined symbols are either imported or defined by a dynamic object. * coff64-rs6000.c (xcoff64_ppc_relocate_section): Likewise. * xcofflink.c (xcoff_link_add_symbols): Extend function-symbol handling to all relocations. Only set XCOFF_CALLED for function symbols. (xcoff_find_function): New function, split out from... (bfd_xcoff_export_symbol) ...here. (xcoff_set_import_path): New function, split out from... (bfd_xcoff_import_symbol): ...here. Remove assertion for old meaning of XCOFF_CALLED. (xcoff_mark_symbol): If we mark an undefined and unimported symbol, find some way of defining it. If the symbol is a function descriptor, fill in its definition automatically. If the symbol is a function, mark its descriptor and allocate room for global linkage code. Otherwise mark the symbol as implicitly imported. Move the code for creating function descriptors from... (xcoff_build_ldsyms): ...here. Use XCOFF_WAS_UNDEFINED to check for symbols that were implicitly defined. (xcoff_mark): Don't count any dynamic relocations against function symbols. (bfd_xcoff_size_dynamic_sections): Save the rtld parameter in the xcoff link info. (xcoff_link_input_bfd): Remove handling of undefined and unexported symbols. ld/ * emultempl/aix.em (gld${EMULATION_NAME}_handle_option): Make -berok and -bernotok control link_info.unresolved_syms_in_objects and link_info.unresolved_syms_in_shared_libs instead of force_make_executable. ld/testsuite/ * ld-powerpc/aix-glink-1.ex, ld-powerpc/aix-glink-1.s, ld-powerpc/aix-glink-1-32.dd, ld-powerpc/aix-glink-1-64.dd, ld-powerpc/aix-glink-1-32.d, ld-powerpc/aix-glink-1-64.d: New tests. * ld-powerpc/aix52.exp: Run them.
